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. | |

356 | Error reporting | |
357 | ||
358 | Most BFD functions return nonzero on success (check their | |
359 | individual documentation for precise semantics). On an error, | |
360 | they call <<bfd_set_error>> to set an error condition that callers | |
361 | can check by calling <<bfd_get_error>>. | |
362 | If that returns <<bfd_error_system_call>>, then check | |
363 | <<errno>>. | |
364 | ||
365 | The easiest way to report a BFD error to the user is to | |
366 | use <<bfd_perror>>. | |
