(int @var{descriptor}, off_t @var{offset}, const char *{segment_name}, @

|
|
|
|
Opens an object file for reading. Creates and returns an
|
|
@code{simple_object_read} pointer which may be passed to other
|
|
functions to extract data from the object file.
|
|
|
|
@var{descriptor} holds a file descriptor which permits reading.
|
|
|
|
@var{offset} is the offset into the file; this will be @code{0} in the
|
|
normal case, but may be a different value when reading an object file
|
|
in an archive file.
|
|
|
|
@var{segment_name} is only used with the Mach-O file format used on
|
|
Darwin aka Mac OS X. It is required on that platform, and means to
|
|
only look at sections within the segment with that name. The
|
|
parameter is ignored on other systems.
|
|
|
|
If an error occurs, this functions returns @code{NULL} and sets
|
|
@code{*@var{errmsg}} to an error string and sets @code{*@var{err}} to
|
|
an errno value or @code{0} if there is no relevant errno.

(simple_object_read *@var{simple_object}, int (*@var{pfn}) (void *@var{data}, @
|
|
const char *@var{name}, off_t @var{offset}, off_t @var{length}), @
|
|
void *@var{data}, int *@var{err})
|
|
|
|
This function calls @var{pfn} for each section in @var{simple_object}.
|
|
It calls @var{pfn} with the section name, the offset within the file
|
|
of the section contents, and the length of the section contents. The
|
|
offset within the file is relative to the offset passed to
|
|
@code{simple_object_open_read}. The @var{data} argument to this
|
|
function is passed along to @var{pfn}.
|
|
|
|
If @var{pfn} returns @code{0}, the loop over the sections stops and
|
|
@code{simple_object_find_sections} returns. If @var{pfn} returns some
|
|
other value, the loop continues.
|
|
|
|
On success @code{simple_object_find_sections} returns. On error it
|
|
returns an error string, and sets @code{*@var{err}} to an errno value
|
|
or @code{0} if there is no relevant errno.

|
|
|
|
Look for the section @var{name} in @var{simple_object}. This returns
|
|
information for the first section with that name.
|
|
|
|
If found, return 1 and set @code{*@var{offset}} to the offset in the
|
|
file of the section contents and set @code{*@var{length}} to the
|
|
length of the section contents. The value in @code{*@var{offset}}
|
|
will be relative to the offset passed to
|
|
@code{simple_object_open_read}.
|
|
|
|
If the section is not found, and no error occurs,
|
|
@code{simple_object_find_section} returns @code{0} and set

|
@code{*@var{errmsg}} to @code{NULL}.
|
|
|
|
If an error occurs, @code{simple_object_find_section} returns
|
|
@code{0}, sets @code{*@var{errmsg}} to an error message, and sets

|
|
|
|
Fetch the attributes of @var{simple_object}. The attributes are
|
|
internal information such as the format of the object file, or the
|
|
architecture it was compiled for. This information will persist until
|
|
@code{simple_object_attributes_release} is called, even if
|
|
@var{simple_object} itself is released.
|
|
|
|
On error this returns @code{NULL}, sets @code{*@var{errmsg}} to an

error message, and sets @code{*@var{err}} to an errno value or

@code{0} if there is no relevant errno.

Compare @var{attrs1} and @var{attrs2}. If they could be linked
|

together without error, return @code{NULL}. Otherwise, return an

error message and set @code{*@var{err}} to an errno value or @code{0}

const char **@var{errmsg}, int *@var{err})
|
|
|
|
Start creating a new object file using the object file format
|
|
described in @var{attrs}. You must fetch attribute information from
|
|
an existing object file before you can create a new one. There is
|
|
currently no support for creating an object file de novo.
|
|
|
|
@var{segment_name} is only used with Mach-O as found on Darwin aka Mac
|
|
OS X. The parameter is required on that target. It means that all
|
|
sections are created within the named segment. It is ignored for
|
|
other object file formats.
|
|
|
|
On error @code{simple_object_start_write} returns @code{NULL}, sets
|
|
@code{*@var{ERRMSG}} to an error message, and sets @code{*@var{err}}

to an errno value or @code{0} if there is no relevant errno.

|
|
|
|
Add a section to @var{simple_object}. @var{name} is the name of the
|
|
new section. @var{align} is the required alignment expressed as the
|
|
number of required low-order 0 bits (e.g., 2 for alignment to a 32-bit
|
|
boundary).
|
|
|
|
The section is created as containing data, readable, not writable, not
|
|
executable, not loaded at runtime. The section is not written to the
|
|
file until @code{simple_object_write_to_file} is called.
|
|
|
|
On error this returns @code{NULL}, sets @code{*@var{errmsg}} to an

error message, and sets @code{*@var{err}} to an errno value or

@code{0} if there is no relevant errno.

|
|
|
|
Add data @var{buffer}/@var{size} to @var{section} in

|
@var{simple_object}. If @var{copy} is non-zero, the data will be
|
|
copied into memory if necessary. If @var{copy} is zero, @var{buffer}

Write the complete object file to @var{descriptor}, an open file

descriptor. This writes out all the data accumulated by calls to

@code{simple_object_write_create_section} and

@var{simple_object_write_add_data}.
