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

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

823 | Return the file size (as read from file system) for the file | |

826 | The initial motivation for, and use of, this routine is not | |
827 | so we can get the exact size of the object the BFD applies to, since | |
828 | that might not be generally possible (archive members for example). | |
829 | It would be ideal if someone could eventually modify | |
830 | it so that such results were guaranteed. | |
831 | ||
832 | Instead, we want to ask questions like "is this NNN byte sized | |
833 | object I'm about to try read from file offset YYY reasonable?" | |
834 | As as example of where we might do this, some object formats | |
eb6e10cb | 835 | use string tables for which the first <<sizeof (long)>> bytes of the |
252b5132 RH |
836 | table contain the size of the table itself, including the size bytes. |
837 | If an application tries to read what it thinks is one of these | |
838 | string tables, without some way to validate the size, and for | |
839 | some reason the size is wrong (byte swapping error, wrong location | |
840 | for the string table, etc.), the only clue is likely to be a read | |
841 | error when it tries to read the table, or a "virtual memory | |
842 | exhausted" error when it tries to allocate 15 bazillon bytes | |
843 | of space for the 15 bazillon byte table it is about to read. | |
844 | This function at least allows us to answer the quesion, "is the | |
845 | size reasonable?". | |
