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. | |

484 | Error reporting | |
485 | ||
486 | Most BFD functions return nonzero on success (check their | |
487 | individual documentation for precise semantics). On an error, | |
488 | they call <<bfd_set_error>> to set an error condition that callers | |
489 | can check by calling <<bfd_get_error>>. | |
07d6d2b8 | 490 | If that returns <<bfd_error_system_call>>, then check |
252b5132 RH |
491 | <<errno>>. |
492 | ||
493 | The easiest way to report a BFD error to the user is to | |
494 | use <<bfd_perror>>. | |
495 | ||

497 | Type <<bfd_error_type>> | |

1319 | handler is called with information on the BFD version, BFD | |

1322 | the current BFD operation as failed, so it is recommended to | |

1746 | A base of 0 causes the function to interpret the string | |
1747 | in hex if a leading "0x" or "0X" is found, otherwise | |
1748 | in octal if a leading zero is found, otherwise in decimal. | |
