SECTION
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>>.
/** Error handling
o - Most functions return nonzero on success (check doc for
precise semantics); 0 or NULL on error.
o - Internal errors are documented by the value of bfd_error.
If that is system_call_error then check errno.
o - The easiest way to report this to the user is to use bfd_perror.
The easiest way to report a BFD error to the user is to
use <<bfd_perror>>.
SUBSECTION
Type <<bfd_error_type>>
The values returned by <<bfd_get_error>> are defined by the
enumerated type <<bfd_error_type>>.

Set the flag word in the BFD @var{abfd} to the value @var{flags}.
Possible errors are:
o <<wrong_format>> - The target bfd was not of object format.
o <<invalid_operation>> - The target bfd was open for reading.
o <<invalid_operation>> -
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.
