1 What is libffi?
*****************
Compilers for high level languages generate code that follow certain
conventions. These conventions are necessary, in part, for separate
compilation to work. One such convention is the "calling convention".
The calling convention is a set of assumptions made by the compiler
about where function arguments will be found on entry to a function. A
calling convention also specifies where the return value for a function
is found. The calling convention is also sometimes called the "ABI" or
"Application Binary Interface".
Some programs may not know at the time of compilation what arguments
are to be passed to a function. For instance, an interpreter may be
told at run-time about the number and types of arguments used to call a
given function. `Libffi' can be used in such programs to provide a
bridge from the interpreter program to compiled code.
The `libffi' library provides a portable, high level programming
interface to various calling conventions. This allows a programmer to
call any function specified by a call interface description at run time.
FFI stands for Foreign Function Interface. A foreign function
interface is the popular name for the interface that allows code
written in one language to call code written in another language. The
`libffi' library really only provides the lowest, machine dependent
layer of a fully featured foreign function interface. A layer must
exist above `libffi' that handles type conversions for values passed
between the two languages.

2.1 The Basics
==============
`Libffi' assumes that you have a pointer to the function you wish to
call and that you know the number and types of arguments to pass it, as
well as the return type of the function.
The first thing you must do is create an `ffi_cif' object that
matches the signature of the function you wish to call. This is a
separate step because it is common to make multiple calls using a
single `ffi_cif'. The "cif" in `ffi_cif' stands for Call InterFace.
To prepare a call interface object, use the function `ffi_prep_cif'.
-- Function: ffi_status ffi_prep_cif (ffi_cif *CIF, ffi_abi ABI,
unsigned int NARGS, ffi_type *RTYPE, ffi_type **ARGTYPES)
This initializes CIF according to the given parameters.
ABI is the ABI to use; normally `FFI_DEFAULT_ABI' is what you
want. *note Multiple ABIs:: for more information.
NARGS is the number of arguments that this function accepts.
`libffi' does not yet handle varargs functions; see *note Missing
Features:: for more information.
RTYPE is a pointer to an `ffi_type' structure that describes the
return type of the function. *Note Types::.
ARGTYPES is a vector of `ffi_type' pointers. ARGTYPES must have
NARGS elements. If NARGS is 0, this argument is ignored.
`ffi_prep_cif' returns a `libffi' status code, of type
`ffi_status'. This will be either `FFI_OK' if everything worked
properly; `FFI_BAD_TYPEDEF' if one of the `ffi_type' objects is
incorrect; or `FFI_BAD_ABI' if the ABI parameter is invalid.
To call a function using an initialized `ffi_cif', use the
`ffi_call' function:
-- Function: void ffi_call (ffi_cif *CIF, void *FN, void *RVALUE, void
**AVALUES)
This calls the function FN according to the description given in
CIF. CIF must have already been prepared using `ffi_prep_cif'.
RVALUE is a pointer to a chunk of memory that will hold the result
of the function call. This must be large enough to hold the
result and must be suitably aligned; it is the caller's
responsibility to ensure this. If CIF declares that the function
returns `void' (using `ffi_type_void'), then RVALUE is ignored.
If RVALUE is `NULL', then the return value is discarded.
AVALUES is a vector of `void *' pointers that point to the memory
locations holding the argument values for a call. If CIF declares
that the function has no arguments (i.e., NARGS was 0), then
AVALUES is ignored.

2.2 Simple Example
==================
Here is a trivial example that calls `puts' a few times.
#include <stdio.h>
#include <ffi.h>
int main()
{
ffi_cif cif;
ffi_type *args[1];
void *values[1];
char *s;
int rc;
/* Initialize the argument info vectors */
args[0] = &ffi_type_pointer;
values[0] = &s;
/* Initialize the cif */
if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1,
&ffi_type_uint, args) == FFI_OK)
{
s = "Hello World!";
ffi_call(&cif, puts, &rc, values);
/* rc now holds the result of the call to puts */
/* values holds a pointer to the function's arg, so to
call puts() again all we need to do is change the
value of s */
s = "This is cool!";
ffi_call(&cif, puts, &rc, values);
}
return 0;
}

2.3.1 Primitive Types
---------------------
`Libffi' provides a number of built-in type descriptors that can be
used to describe argument and return types:
`ffi_type_void'
The type `void'. This cannot be used for argument types, only for
return values.
`ffi_type_uint8'
An unsigned, 8-bit integer type.
`ffi_type_sint8'
A signed, 8-bit integer type.
`ffi_type_uint16'
An unsigned, 16-bit integer type.
`ffi_type_sint16'
A signed, 16-bit integer type.
`ffi_type_uint32'
An unsigned, 32-bit integer type.
`ffi_type_sint32'
A signed, 32-bit integer type.
`ffi_type_uint64'
An unsigned, 64-bit integer type.
`ffi_type_sint64'
A signed, 64-bit integer type.
`ffi_type_float'
The C `float' type.
`ffi_type_double'
The C `double' type.
`ffi_type_uchar'
The C `unsigned char' type.
`ffi_type_schar'
The C `signed char' type. (Note that there is not an exact
equivalent to the C `char' type in `libffi'; ordinarily you should
either use `ffi_type_schar' or `ffi_type_uchar' depending on
whether `char' is signed.)
`ffi_type_ushort'
The C `unsigned short' type.
`ffi_type_sshort'
The C `short' type.
`ffi_type_uint'
The C `unsigned int' type.
`ffi_type_sint'
The C `int' type.
`ffi_type_ulong'
The C `unsigned long' type.
`ffi_type_slong'
The C `long' type.
`ffi_type_longdouble'
On platforms that have a C `long double' type, this is defined.
On other platforms, it is not.
`ffi_type_pointer'
A generic `void *' pointer. You should use this for all pointers,
regardless of their real type.
Each of these is of type `ffi_type', so you must take the address
when passing to `ffi_prep_cif'.

File: libffi.info, Node: Structures, Next: Type Example, Prev: Primitive Types, Up: Types
2.3.2 Structures
----------------
Although `libffi' has no special support for unions or bit-fields, it
is perfectly happy passing structures back and forth. You must first
describe the structure to `libffi' by creating a new `ffi_type' object
for it.
-- ffi_type:
The `ffi_type' has the following members:
`size_t size'
This is set by `libffi'; you should initialize it to zero.
`unsigned short alignment'
This is set by `libffi'; you should initialize it to zero.
`unsigned short type'
For a structure, this should be set to `FFI_TYPE_STRUCT'.
`ffi_type **elements'
This is a `NULL'-terminated array of pointers to `ffi_type'
objects. There is one element per field of the struct.

File: libffi.info, Node: Type Example, Prev: Structures, Up: Types
2.3.3 Type Example
------------------
The following example initializes a `ffi_type' object representing the
`tm' struct from Linux's `time.h'.
Here is how the struct is defined:
struct tm {
int tm_sec;
int tm_min;
int tm_hour;
int tm_mday;
int tm_mon;
int tm_year;
int tm_wday;
int tm_yday;
int tm_isdst;
/* Those are for future use. */
long int __tm_gmtoff__;
__const char *__tm_zone__;
};
Here is the corresponding code to describe this struct to `libffi':
{
ffi_type tm_type;
ffi_type *tm_type_elements[12];
int i;
tm_type.size = tm_type.alignment = 0;
tm_type.elements = &tm_type_elements;
for (i = 0; i < 9; i++)
tm_type_elements[i] = &ffi_type_sint;
tm_type_elements[9] = &ffi_type_slong;
tm_type_elements[10] = &ffi_type_pointer;
tm_type_elements[11] = NULL;
/* tm_type can now be used to represent tm argument types and
return types for ffi_prep_cif() */
}

File: libffi.info, Node: Multiple ABIs, Next: The Closure API, Prev: Types, Up: Using libffi
2.4 Multiple ABIs
=================
A given platform may provide multiple different ABIs at once. For
instance, the x86 platform has both `stdcall' and `fastcall' functions.
`libffi' provides some support for this. However, this is
necessarily platform-specific.

File: libffi.info, Node: The Closure API, Prev: Multiple ABIs, Up: Using libffi
2.5 The Closure API
===================
`libffi' also provides a way to write a generic function - a function
that can accept and decode any combination of arguments. This can be
useful when writing an interpreter, or to provide wrappers for
arbitrary functions.
This facility is called the "closure API". Closures are not
supported on all platforms; you can check the `FFI_CLOSURES' define to
determine whether they are supported on the current platform.
Because closures work by assembling a tiny function at runtime, they
require special allocation on platforms that have a non-executable
heap. Memory management for closures is handled by a pair of functions:
-- Function: void *ffi_closure_alloc (size_t SIZE, void **CODE)
Allocate a chunk of memory holding SIZE bytes. This returns a
pointer to the writable address, and sets *CODE to the
corresponding executable address.
SIZE should be sufficient to hold a `ffi_closure' object.
-- Function: void ffi_closure_free (void *WRITABLE)
Free memory allocated using `ffi_closure_alloc'. The argument is
the writable address that was returned.
Once you have allocated the memory for a closure, you must construct
a `ffi_cif' describing the function call. Finally you can prepare the
closure function:
-- Function: ffi_status ffi_prep_closure_loc (ffi_closure *CLOSURE,
ffi_cif *CIF, void (*FUN) (ffi_cif *CIF, void *RET, void
**ARGS, void *USER_DATA), void *USER_DATA, void *CODELOC)
Prepare a closure function.
CLOSURE is the address of a `ffi_closure' object; this is the
writable address returned by `ffi_closure_alloc'.
CIF is the `ffi_cif' describing the function parameters.
USER_DATA is an arbitrary datum that is passed, uninterpreted, to
your closure function.
CODELOC is the executable address returned by `ffi_closure_alloc'.
FUN is the function which will be called when the closure is
invoked. It is called with the arguments:
CIF
The `ffi_cif' passed to `ffi_prep_closure_loc'.
RET
A pointer to the memory used for the function's return value.
FUN must fill this, unless the function is declared as
returning `void'.
ARGS
A vector of pointers to memory holding the arguments to the
function.
USER_DATA
The same USER_DATA that was passed to `ffi_prep_closure_loc'.
`ffi_prep_closure_loc' will return `FFI_OK' if everything went ok,
and something else on error.
After calling `ffi_prep_closure_loc', you can cast CODELOC to the
appropriate pointer-to-function type.
You may see old code referring to `ffi_prep_closure'. This function
is deprecated, as it cannot handle the need for separate writable and
executable addresses.

3 Missing Features
******************
`libffi' is missing a few features. We welcome patches to add support
for these.
* There is no support for calling varargs functions. This may work
on some platforms, depending on how the ABI is defined, but it is
not reliable.
* There is no support for bit fields in structures.
* The closure API is
* The "raw" API is undocumented.

@section The Basics
@samp{Libffi} assumes that you have a pointer to the function you wish
to call and that you know the number and types of arguments to pass
it, as well as the return type of the function.
The first thing you must do is create an @code{ffi_cif} object that
matches the signature of the function you wish to call. This is a
separate step because it is common to make multiple calls using a
single @code{ffi_cif}. The @dfn{cif} in @code{ffi_cif} stands for
Call InterFace. To prepare a call interface object, use the function
@code{ffi_prep_cif}.
@cindex cif
@findex ffi_prep_cif
@defun ffi_status ffi_prep_cif (ffi_cif *@var{cif}, ffi_abi @var{abi}, unsigned int @var{nargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes})
This initializes @var{cif} according to the given parameters.
@var{abi} is the ABI to use; normally @code{FFI_DEFAULT_ABI} is what
you want. @ref{Multiple ABIs} for more information.
@var{nargs} is the number of arguments that this function accepts.
@samp{libffi} does not yet handle varargs functions; see @ref{Missing
Features} for more information.
@var{rtype} is a pointer to an @code{ffi_type} structure that
describes the return type of the function. @xref{Types}.
@var{argtypes} is a vector of @code{ffi_type} pointers.
@var{argtypes} must have @var{nargs} elements. If @var{nargs} is 0,
this argument is ignored.
@code{ffi_prep_cif} returns a @code{libffi} status code, of type
@code{ffi_status}. This will be either @code{FFI_OK} if everything
worked properly; @code{FFI_BAD_TYPEDEF} if one of the @code{ffi_type}
objects is incorrect; or @code{FFI_BAD_ABI} if the @var{abi} parameter
is invalid.
@end defun
To call a function using an initialized @code{ffi_cif}, use the
@code{ffi_call} function:
@findex ffi_call
@defun void ffi_call (ffi_cif *@var{cif}, void *@var{fn}, void *@var{rvalue}, void **@var{avalues})
This calls the function @var{fn} according to the description given in
@var{cif}. @var{cif} must have already been prepared using
@code{ffi_prep_cif}.
@var{rvalue} is a pointer to a chunk of memory that will hold the
result of the function call. This must be large enough to hold the
result and must be suitably aligned; it is the caller's responsibility
to ensure this. If @var{cif} declares that the function returns
@code{void} (using @code{ffi_type_void}), then @var{rvalue} is
ignored. If @var{rvalue} is @samp{NULL}, then the return value is
discarded.
@var{avalues} is a vector of @code{void *} pointers that point to the
memory locations holding the argument values for a call. If @var{cif}
declares that the function has no arguments (i.e., @var{nargs} was 0),
then @var{avalues} is ignored.

pointers, regardless of their real type.
@end table
Each of these is of type @code{ffi_type}, so you must take the address
when passing to @code{ffi_prep_cif}.
@node Structures
@subsection Structures
Although @samp{libffi} has no special support for unions or
bit-fields, it is perfectly happy passing structures back and forth.
You must first describe the structure to @samp{libffi} by creating a
new @code{ffi_type} object for it.
@tindex ffi_type
@deftp ffi_type
The @code{ffi_type} has the following members:
@table @code
@item size_t size
This is set by @code{libffi}; you should initialize it to zero.
@item unsigned short alignment
This is set by @code{libffi}; you should initialize it to zero.
@item unsigned short type
For a structure, this should be set to @code{FFI_TYPE_STRUCT}.
@item ffi_type **elements
This is a @samp{NULL}-terminated array of pointers to @code{ffi_type}
objects. There is one element per field of the struct.
@end table
@end deftp
@node Type Example
@subsection Type Example
The following example initializes a @code{ffi_type} object
representing the @code{tm} struct from Linux's @file{time.h}.
Here is how the struct is defined:
@example
struct tm @{
int tm_sec;
int tm_min;
int tm_hour;
int tm_mday;
int tm_mon;
int tm_year;
int tm_wday;
int tm_yday;
int tm_isdst;
/* Those are for future use. */
long int __tm_gmtoff__;
__const char *__tm_zone__;
@};
@end example
Here is the corresponding code to describe this struct to
@code{libffi}:
@example
@{
ffi_type tm_type;
ffi_type *tm_type_elements[12];
int i;
tm_type.size = tm_type.alignment = 0;
tm_type.elements = &tm_type_elements;
for (i = 0; i < 9; i++)
tm_type_elements[i] = &ffi_type_sint;
tm_type_elements[9] = &ffi_type_slong;
tm_type_elements[10] = &ffi_type_pointer;
tm_type_elements[11] = NULL;
/* tm_type can now be used to represent tm argument types and
return types for ffi_prep_cif() */
@}
@end example
@node Multiple ABIs
@section Multiple ABIs
A given platform may provide multiple different ABIs at once. For
instance, the x86 platform has both @samp{stdcall} and @samp{fastcall}
functions.
@code{libffi} provides some support for this. However, this is
necessarily platform-specific.
@c FIXME: document the platforms
@node The Closure API
@section The Closure API
@code{libffi} also provides a way to write a generic function -- a
function that can accept and decode any combination of arguments.
This can be useful when writing an interpreter, or to provide wrappers
for arbitrary functions.
This facility is called the @dfn{closure API}. Closures are not
supported on all platforms; you can check the @code{FFI_CLOSURES}
define to determine whether they are supported on the current
platform.
@cindex closures
@cindex closure API
@findex FFI_CLOSURES
Because closures work by assembling a tiny function at runtime, they
require special allocation on platforms that have a non-executable
heap. Memory management for closures is handled by a pair of
functions:
@findex ffi_closure_alloca
@defun void *ffi_closure_alloc (size_t @var{size}, void **@var{code})
Allocate a chunk of memory holding @var{size} bytes. This returns a
pointer to the writable address, and sets *@var{code} to the
corresponding executable address.
@var{size} should be sufficient to hold a @code{ffi_closure} object.
@end defun
@findex ffi_closure_free
@defun void ffi_closure_free (void *@var{writable})
Free memory allocated using @code{ffi_closure_alloc}. The argument is
the writable address that was returned.
@end defun
Once you have allocated the memory for a closure, you must construct a
@code{ffi_cif} describing the function call. Finally you can prepare
the closure function:
@findex ffi_prep_closure_loc
@defun ffi_status ffi_prep_closure_loc (ffi_closure *@var{closure}, ffi_cif *@var{cif}, void (*@var{fun}) (ffi_cif *@var{cif}, void *@var{ret}, void **@var{args}, void *@var{user_data}), void *@var{user_data}, void *@var{codeloc})
Prepare a closure function.
@var{closure} is the address of a @code{ffi_closure} object; this is
the writable address returned by @code{ffi_closure_alloc}.
@var{cif} is the @code{ffi_cif} describing the function parameters.
@var{user_data} is an arbitrary datum that is passed, uninterpreted,
to your closure function.
@var{codeloc} is the executable address returned by
@code{ffi_closure_alloc}.
@var{fun} is the function which will be called when the closure is
invoked. It is called with the arguments:
@table @var
@item cif
The @code{ffi_cif} passed to @code{ffi_prep_closure_loc}.
@item ret
A pointer to the memory used for the function's return value.
@var{fun} must fill this, unless the function is declared as returning
@code{void}.
@c FIXME: is this NULL for void-returning functions?
@item args
A vector of pointers to memory holding the arguments to the function.
@item user_data
The same @var{user_data} that was passed to
@code{ffi_prep_closure_loc}.
@end table
@code{ffi_prep_closure_loc} will return @code{FFI_OK} if everything
went ok, and something else on error.
@c FIXME: what?
After calling @code{ffi_prep_closure_loc}, you can cast @var{codeloc}
to the appropriate pointer-to-function type.
@end defun
@c FIXME: example
You may see old code referring to @code{ffi_prep_closure}. This
function is deprecated, as it cannot handle the need for separate
writable and executable addresses.
@node Missing Features
@chapter Missing Features
@code{libffi} is missing a few features. We welcome patches to add
support for these.
@itemize @bullet
@item
There is no support for calling varargs functions. This may work on
some platforms, depending on how the ABI is defined, but it is not
reliable.
@item
There is no support for bit fields in structures.
@item
The closure API is
@item
The ``raw'' API is undocumented.
@c argument promotion?
@c unions?
@c anything else?

.Sh NAME
.Nm ffi_call
.Nd Invoke a foreign function.
.Sh SYNOPSIS
.In ffi.h
.Ft void
.Fo ffi_call
.Fa "ffi_cif *cif"
.Fa "void (*fn)(void)"
.Fa "void *rvalue"
.Fa "void **avalue"
.Fc
.Sh DESCRIPTION
The
.Nm ffi_call
function provides a simple mechanism for invoking a function without
requiring knowledge of the function's interface at compile time.
.Fa fn
is called with the values retrieved from the pointers in the
.Fa avalue
array. The return value from
.Fa fn
is placed in storage pointed to by
.Fa rvalue .
.Fa cif
contains information describing the data types, sizes and alignments of the
arguments to and return value from
.Fa fn ,
and must be initialized with
.Nm ffi_prep_cif
before it is used with
.Nm ffi_call .
.Pp
.Fa rvalue
must point to storage that is sizeof(long) or larger. For smaller
return value sizes, the
.Nm ffi_arg
or
.Nm ffi_sarg
integral type must be used to hold
the return value.
.Sh EXAMPLES
.Bd -literal
#include <ffi/ffi.h>
#include <stdio.h>
unsigned char
foo(unsigned int, float);
int
main(int argc, const char **argv)
{
ffi_cif cif;
ffi_type *arg_types[2];
void *arg_values[2];
ffi_status status;
// Because the return value from foo() is smaller than sizeof(long), it
// must be passed as ffi_arg or ffi_sarg.
ffi_arg result;
// Specify the data type of each argument. Available types are defined
// in <ffi/ffi.h>.
arg_types[0] = &ffi_type_uint;
arg_types[1] = &ffi_type_float;
// Prepare the ffi_cif structure.
if ((status = ffi_prep_cif(&cif, FFI_DEFAULT_ABI,
2, &ffi_type_uint8, arg_types)) != FFI_OK)
{
// Handle the ffi_status error.
}
// Specify the values of each argument.
unsigned int arg1 = 42;
float arg2 = 5.1;
arg_values[0] = &arg1;
arg_values[1] = &arg2;
// Invoke the function.
ffi_call(&cif, FFI_FN(foo), &result, arg_values);
// The ffi_arg 'result' now contains the unsigned char returned from foo(),
// which can be accessed by a typecast.
printf("result is %hhu", (unsigned char)result);
return 0;
}
// The target function.
unsigned char
foo(unsigned int x, float y)
{
unsigned char result = x - y;
return result;
}

.Sh DESCRIPTION
The
.Nm ffi_prep_cif
function prepares a
.Nm ffi_cif
structure for use with
.Nm ffi_call
.
.Fa abi
specifies a set of calling conventions to use.
.Fa atypes
is an array of
.Fa nargs
pointers to
.Nm ffi_type
structs that describe the data type, size and alignment of each argument.
.Fa rtype
points to an
.Nm ffi_type
that describes the data type, size and alignment of the
return value.
.Sh RETURN VALUES
Upon successful completion,
.Nm ffi_prep_cif
returns
.Nm FFI_OK .
It will return
.Nm FFI_BAD_TYPEDEF
if
.Fa cif
is
.Nm NULL
or
.Fa atypes
or
.Fa rtype
is malformed. If
.Fa abi
does not refer to a valid ABI,
.Nm FFI_BAD_ABI
will be returned. Available ABIs are
defined in
.Nm <ffitarget.h>
