28 | A BFD has type <<bfd>>; objects of this type are the | |
29 | cornerstone of any application using BFD. Using BFD | |
30 | consists of making references though the BFD and to data in the BFD. | |
31 | ||
32 | Here is the structure that defines the type <<bfd>>. It | |
33 | contains the major data about the file and pointers | |
34 | to the rest of the data. | |

344 | Error reporting | |
345 | ||
346 | Most BFD functions return nonzero on success (check their | |
347 | individual documentation for precise semantics). On an error, | |
348 | they call <<bfd_set_error>> to set an error condition that callers | |
349 | can check by calling <<bfd_get_error>>. | |
350 | If that returns <<bfd_error_system_call>>, then check | |
351 | <<errno>>. | |
352 | ||
353 | The easiest way to report a BFD error to the user is to | |
354 | use <<bfd_perror>>. | |
