26 | ||
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. | |

225 | Error reporting | |
226 | ||
227 | Most BFD functions return nonzero on success (check their | |
228 | individual documentation for precise semantics). On an error, | |
229 | they call <<bfd_set_error>> to set an error condition that callers | |
230 | can check by calling <<bfd_get_error>>. | |
231 | If that returns <<bfd_error_system_call>>, then check | |
232 | <<errno>>. | |
233 | ||
234 | The easiest way to report a BFD error to the user is to | |
235 | use <<bfd_perror>>. | |

867 | so we can get the exact size of the object the BFD applies to, since | |
868 | that might not be generally possible (archive members for example). | |
869 | It would be ideal if someone could eventually modify | |
870 | it so that such results were guaranteed. | |
871 | ||
872 | Instead, we want to ask questions like "is this NNN byte sized | |
873 | object I'm about to try read from file offset YYY reasonable?" | |
874 | As as example of where we might do this, some object formats | |
eb6e10cb | 875 | use string tables for which the first <<sizeof (long)>> bytes of the |
252b5132 RH |
876 | table contain the size of the table itself, including the size bytes. |
877 | If an application tries to read what it thinks is one of these | |
878 | string tables, without some way to validate the size, and for | |
879 | some reason the size is wrong (byte swapping error, wrong location | |
880 | for the string table, etc.), the only clue is likely to be a read | |
881 | error when it tries to read the table, or a "virtual memory | |
882 | exhausted" error when it tries to allocate 15 bazillon bytes | |
883 | of space for the 15 bazillon byte table it is about to read. | |
884 | This function at least allows us to answer the quesion, "is the | |
885 | size reasonable?". | |
