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. | |
32 | ||
33 | Here is the structure that defines the type <<bfd>>. It | |
34 | contains the major data about the file and pointers | |
35 | to the rest of the data. | |

634 | Error reporting | |
635 | ||
636 | Most BFD functions return nonzero on success (check their | |
637 | individual documentation for precise semantics). On an error, | |
638 | they call <<bfd_set_error>> to set an error condition that callers | |
639 | can check by calling <<bfd_get_error>>. | |
07d6d2b8 | 640 | If that returns <<bfd_error_system_call>>, then check |
252b5132 RH |
641 | <<errno>>. |
642 | ||
643 | The easiest way to report a BFD error to the user is to | |
644 | use <<bfd_perror>>. | |
645 | ||
646 | SUBSECTION | |
647 | Type <<bfd_error_type>> | |

832 | by @var{message}, a colon, and a space. It is followed by a newline. | |

850 | Some BFD functions want to print messages describing the | |
