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. | |

622 | Error reporting | |
623 | ||
624 | Most BFD functions return nonzero on success (check their | |
625 | individual documentation for precise semantics). On an error, | |
626 | they call <<bfd_set_error>> to set an error condition that callers | |
627 | can check by calling <<bfd_get_error>>. | |
07d6d2b8 | 628 | If that returns <<bfd_error_system_call>>, then check |
252b5132 RH |
629 | <<errno>>. |
630 | ||
631 | The easiest way to report a BFD error to the user is to | |
632 | use <<bfd_perror>>. | |

836 | BFD error handler | |
837 | ||
838 | Some BFD functions want to print messages describing the | |
839 | problem. They call a BFD error handler function. This | |
5c4491d3 | 840 | function may be overridden by the program. |
252b5132 | 841 | |
52d45da3 | 842 | The BFD error handler acts like vprintf. |
