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

235 | Most BFD functions return nonzero on success (check their | |
236 | individual documentation for precise semantics). On an error, | |
237 | they call <<bfd_set_error>> to set an error condition that callers | |

239 | If that returns <<bfd_error_system_call>>, then check | |
240 | <<errno>>. | |

1446 | DESCRIPTION | |
1447 | When testing an object for compatibility with a particular | |

1449 | up certain fields in the bfd on successfully recognizing the | |

1451 | failures possible at many points. On failure, the bfd is | |
1452 | supposed to be restored to its initial state, which is | |
1453 | virtually impossible. However, restoring a subset of the bfd | |
1454 | state works in practice. This function stores the subset and | |
1455 | reinitializes the bfd. | |
