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. | |

399 | Error reporting | |
400 | ||
401 | Most BFD functions return nonzero on success (check their | |
402 | individual documentation for precise semantics). On an error, | |
403 | they call <<bfd_set_error>> to set an error condition that callers | |
404 | can check by calling <<bfd_get_error>>. | |
405 | If that returns <<bfd_error_system_call>>, then check | |
406 | <<errno>>. | |
407 | ||
408 | The easiest way to report a BFD error to the user is to | |
409 | use <<bfd_perror>>. | |
410 | ||
411 | SUBSECTION | |
412 | Type <<bfd_error_type>> | |

414 | The values returned by <<bfd_get_error>> are defined by the | |
