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. | |

394 | Error reporting | |
395 | ||
396 | Most BFD functions return nonzero on success (check their | |
397 | individual documentation for precise semantics). On an error, | |
398 | they call <<bfd_set_error>> to set an error condition that callers | |
399 | can check by calling <<bfd_get_error>>. | |
07d6d2b8 | 400 | If that returns <<bfd_error_system_call>>, then check |
252b5132 RH |
401 | <<errno>>. |
402 | ||
403 | The easiest way to report a BFD error to the user is to | |
404 | use <<bfd_perror>>. | |
405 | ||
406 | SUBSECTION | |
407 | Type <<bfd_error_type>> | |

2516 | if needed. The original buffer pointed to by @var{*ptr} may | |
2517 | be freed and @var{*ptr} is returned with memory malloc'd by this | |
cbd44e24 | 2518 | function, and the new size written to @var{ptr_size}. |
