File formats

|
|
|
|
|
|
A format is a BFD concept of high level file contents type. The
|
2001-01-23 21:27:54 +01:00
|
|
|
formats supported by BFD are:
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
o <<bfd_object>>
|
|
|
|
|
|
|
|
The BFD may contain data, symbols, relocations and debug info.
|
|
|
|
|
|
|
|
o <<bfd_archive>>
|
|
|
|
|
|
|
|
The BFD contains other BFDs and an optional index.
|
|
|
|
|
|
|
|
o <<bfd_core>>
|
|
|
|
|
|
|
|
The BFD contains the result of an executable core dump.

|
SYNOPSIS
|
|
|
|
boolean bfd_check_format(bfd *abfd, bfd_format format);
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
Verify if the file attached to the BFD @var{abfd} is compatible
|
|
|
|
with the format @var{format} (i.e., one of <<bfd_object>>,
|
|
|
|
<<bfd_archive>> or <<bfd_core>>).
|
|
|
|
|
|
|
|
If the BFD has been set to a specific target before the
|
|
|
|
call, only the named target and format combination is
|
|
|
|
checked. If the target has not been set, or has been set to
|
|
|
|
<<default>>, then all the known target backends is
|
|
|
|
interrogated to determine a match. If the default target
|
|
|
|
matches, it is used. If not, exactly one target must recognize
|
|
|
|
the file, or an error results.
|
|
|
|
|
|
|
|
The function returns <<true>> on success, otherwise <<false>>
|
2001-01-23 21:27:54 +01:00
|
|
|
with one of the following error codes:
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
o <<bfd_error_invalid_operation>> -
|
|
|
|
if <<format>> is not one of <<bfd_object>>, <<bfd_archive>> or
|
|
|
|
<<bfd_core>>.
|
|
|
|
|
|
|
|
o <<bfd_error_system_call>> -
|
|
|
|
if an error occured during a read - even some file mismatches
|
|
|
|
can cause bfd_error_system_calls.
|
|
|
|
|
|
|
|
o <<file_not_recognised>> -
|
|
|
|
none of the backends recognised the file format.
|
|
|
|
|
|
|
|
o <<bfd_error_file_ambiguously_recognized>> -
|
|
|
|
more than one backend recognised the file format.

DESCRIPTION
|
|
|
|
Like <<bfd_check_format>>, except when it returns false with
|
|
|
|
<<bfd_errno>> set to <<bfd_error_file_ambiguously_recognized>>. In that

|
case, if @var{matching} is not NULL, it will be filled in with

|
|
a NULL-terminated list of the names of the formats that matched,
|

|
|
allocated with <<malloc>>.
|
|
|
|
Then the user may choose a format and try again.
|
|
|
|
|
|
|
|
When done with the list that @var{matching} points to, the caller
|
2001-01-23 21:27:54 +01:00
