29 A BFD has type <<bfd>>; objects of this type are the
30 cornerstone of any application using BFD. Using BFD
31 consists of making references though the BFD and to data in the BFD.

34 contains the major data about the file and pointers
35 to the rest of the data.

613 Error reporting, Miscellaneous, typedef bfd, BFD front end
618 Most BFD functions return nonzero on success (check their
619 individual documentation for precise semantics). On an error,
620 they call <<bfd_set_error>> to set an error condition that callers
621 can check by calling <<bfd_get_error>>.
622 If that returns <<bfd_error_system_call>>, then check
625 The easiest way to report a BFD error to the user is to
629 Type <<bfd_error_type>>
