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. | |

237 | Most BFD functions return nonzero on success (check their | |
238 | individual documentation for precise semantics). On an error, | |
239 | they call <<bfd_set_error>> to set an error condition that callers | |
240 | can check by calling <<bfd_get_error>>. | |
241 | If that returns <<bfd_error_system_call>>, then check | |
242 | <<errno>>. | |

430 | Some BFD functions want to print messages describing the | |

434 | The BFD error handler acts like printf. | |

452 | Note - because these two extra format specifiers require special handling | |

459 | "blah %s blah %A blah %d blah %B" | |

1486 | up certain fields in the bfd on successfully recognizing the | |

1489 | supposed to be restored to its initial state, which is | |
1490 | virtually impossible. However, restoring a subset of the bfd | |
1491 | state works in practice. This function stores the subset and | |

1712 | SYNOPSIS | |
1713 | char *bfd_demangle (bfd *, const char *, int); | |
1714 | ||
1715 | DESCRIPTION | |
1716 | Wrapper around cplus_demangle. Strips leading underscores and | |
1717 | other such chars that would otherwise confuse the demangler. | |
1718 | If passed a g++ v3 ABI mangled name, returns a buffer allocated | |
1719 | with malloc holding the demangled name. Returns NULL otherwise | |
1720 | and on memory alloc failure. | |
