A BFD has type <<bfd>>; objects of this type are the
|
|
|
|
|
cornerstone of any application using BFD. Using BFD
|
|
|
|
|
consists of making references though the BFD and to data in the BFD.
|
|
|
|
|
|
|
|
|
|
Here is the structure that defines the type <<bfd>>. It
|
|
|
|
|
contains the major data about the file and pointers
|
|
|
|
|
to the rest of the data.

Error reporting

|
|
|
|
|
|
|
|
|
Most BFD functions return nonzero on success (check their
|
|
|
|
|
individual documentation for precise semantics). On an error,
|
|
|
|
|
they call <<bfd_set_error>> to set an error condition that callers
|
|
|
|
|
can check by calling <<bfd_get_error>>.
|
|
|
|
|
If that returns <<bfd_error_system_call>>, then check
|
|
|
|
|
<<errno>>.
|
|
|
|
|
|
|
|
|
|
The easiest way to report a BFD error to the user is to
|
|
|
|
|
use <<bfd_perror>>.

BFD error handler

Some BFD functions want to print messages describing the

|
|
problem. They call a BFD error handler function. This
|
|
|
|
|
function may be overriden by the program.
|

|
|
|
|
|
The BFD error handler acts like printf.

|

DESCRIPTION
|

|
|
|
Set the flag word in the BFD @var{abfd} to the value @var{flags}.
|
|
|
|
|
|
|
|
|
|
Possible errors are:
|
|
|
|
|
o <<bfd_error_wrong_format>> - The target bfd was not of object format.
|
|
|
|
|
o <<bfd_error_invalid_operation>> - The target bfd was open for reading.
|
|
|
|
|
o <<bfd_error_invalid_operation>> -
|
|
|
|
|
The flag word contained a bit which was not applicable to the
|
|
|
|
|
type of file. E.g., an attempt was made to set the <<D_PAGED>> bit
|
|
|
|
|
on a BFD format which does not support demand paging.

FUNCTION

|

|
SYNOPSIS
|
2003-02-14 19:16:09 +08:00

|
|
|
bfd_vma bfd_scan_vma (const char *string, const char **end, int base);

|

|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
Convert, like <<strtoul>>, a numerical expression
|
|
|
|
|
@var{string} into a <<bfd_vma>> integer, and return that integer.
|
|
|
|
|
(Though without as many bells and whistles as <<strtoul>>.)
|
|
|
|
|
The expression is assumed to be unsigned (i.e., positive).
|
|
|
|
|
If given a @var{base}, it is used as the base for conversion.
|
|
|
|
|
A base of 0 causes the function to interpret the string
|
|
|
|
|
in hex if a leading "0x" or "0X" is found, otherwise
|
|
|
|
|
in octal if a leading zero is found, otherwise in decimal.
|
|
|
|
|
|
2002-02-15 08:20:17 +08:00
|
|
|
|
If the value would overflow, the maximum <<bfd_vma>> value is
|
|
|
|
|
returned.

SYNOPSIS

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
When more than one machine code number is available for the
|
|
|
|
|
same machine type, this function can be used to switch between
|
2002-07-31 17:38:04 +08:00
|
|
|
|
the preferred one (alternative == 0) and any others. Currently,
|
2001-08-24 21:55:55 +08:00
|
|
|
|
only ELF supports this feature, with up to two alternate
|
|
|
|
|
machine codes.

SYNOPSIS

|
|
DESCRIPTION
|
|
|
|
|
When testing an object for compatibility with a particular
|
|
|
|
|
target back-end, the back-end object_p function needs to set
|
|
|
|
|
up certain fields in the bfd on successfully recognizing the
|
|
|
|
|
object. This typically happens in a piecemeal fashion, with
|
|
|
|
|
failures possible at many points. On failure, the bfd is
|
|
|
|
|
supposed to be restored to its initial state, which is
|
|
|
|
|
virtually impossible. However, restoring a subset of the bfd
|
|
|
|
|
state works in practice. This function stores the subset and
|
|
|
|
|
reinitializes the bfd.
