A format is a BFD concept of high level file contents type. The formats supported by BFD are:
bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
Verify if the file attached to the BFD abfd is compatible with the format format (i.e., one of
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
with one of the following error codes:
formatis not one of
bfd_error_system_call- if an error occured during a read - even some file mismatches can cause bfd_error_system_calls.
file_not_recognised- none of the backends recognised the file format.
bfd_error_file_ambiguously_recognized- more than one backend recognised the file format.
bfd_boolean bfd_check_format_matches (bfd *abfd, bfd_format format, char ***matching);
bfd_check_format, except when it returns FALSE with
bfd_errno set to
bfd_error_file_ambiguously_recognized. In that
case, if matching is not NULL, it will be filled in with
a NULL-terminated list of the names of the formats that matched,
Then the user may choose a format and try again.
When done with the list that matching points to, the caller should free it.
bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
This function sets the file format of the BFD abfd to the format format. If the target set in the BFD does not support the format requested, the format is invalid, or the BFD is not open for writing, then an error occurs.
const char *bfd_format_string (bfd_format format);
Return a pointer to a const string
depending upon the value of format.
