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. | |

229 | Error reporting | |
230 | ||
231 | Most BFD functions return nonzero on success (check their | |
232 | individual documentation for precise semantics). On an error, | |
233 | they call <<bfd_set_error>> to set an error condition that callers | |
234 | can check by calling <<bfd_get_error>>. | |
235 | If that returns <<bfd_error_system_call>>, then check | |
236 | <<errno>>. | |
237 | ||
238 | The easiest way to report a BFD error to the user is to | |
239 | use <<bfd_perror>>. | |

897 | DESCRIPTION | |
898 | Convert, like <<strtoul>>, a numerical expression | |
899 | @var{string} into a <<bfd_vma>> integer, and return that integer. | |
900 | (Though without as many bells and whistles as <<strtoul>>.) | |
901 | The expression is assumed to be unsigned (i.e., positive). | |
902 | If given a @var{base}, it is used as the base for conversion. | |
903 | A base of 0 causes the function to interpret the string | |
904 | in hex if a leading "0x" or "0X" is found, otherwise | |
905 | in octal if a leading zero is found, otherwise in decimal. | |
906 | ||

1293 | |
1294 | DESCRIPTION | |
1295 | When testing an object for compatibility with a particular | |
1296 | target back-end, the back-end object_p function needs to set | |
1297 | up certain fields in the bfd on successfully recognizing the | |
1298 | object. This typically happens in a piecemeal fashion, with | |
1299 | failures possible at many points. On failure, the bfd is | |
1300 | supposed to be restored to its initial state, which is | |
1301 | virtually impossible. However, restoring a subset of the bfd | |
1302 | state works in practice. This function stores the subset and | |
1303 | reinitializes the bfd. | |
