+FUNCTION

+SYNOPSIS
+ bfd_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>>
+ with one of the following error codes:
+
+ 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.
