bfd_check_format
SYNOPSIS

DESCRIPTION
Verify if the file attached to the BFD @var{abfd} is compatible
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>>
+ The function returns <<TRUE>> on success, otherwise <<FALSE>>
with one of the following error codes:
o <<bfd_error_invalid_operation>> -
more than one backend recognised the file format.
