25 | A BFD is has type <<bfd>>; objects of this type are the |
26 | cornerstone of any application using <<libbfd>>. References | |

d3e667e8 | 31 | contains the major data about the file, and contains pointers |

528 | The bfd_get_size function | |
529 | ||
530 | SYNOPSIS | |
531 | long bfd_get_size(bfd *); | |
532 | ||
533 | DESCRIPTION | |
534 | Return file size (as read from file system) for the file | |
535 | associated with a bfd. | |
536 | ||
537 | Note that the initial motivation for, and use of, this routine is not | |
538 | so we can get the exact size of the object the bfd applies to, since | |
539 | that might not be generally possible (archive members for example?). | |
540 | Although it would be ideal if someone could eventually modify | |
541 | it so that such results were guaranteed. | |
542 | ||
543 | Instead, we want to ask questions like "is this NNN byte sized | |
544 | object I'm about to try read from file offset YYY reasonable?" | |
545 | As as example of where we might want to do this, some object formats | |
546 | use string tables for which the first sizeof(long) bytes of the table | |
547 | contain the size of the table itself, including the size bytes. | |
548 | If an application tries to read what it thinks is one of these | |
549 | string tables, without some way to validate the size, and for | |
550 | some reason the size is wrong (byte swapping error, wrong location | |
551 | for the string table, etc), the only clue is likely to be a read | |
552 | error when it tries to read the table, or a "virtual memory | |
553 | exhausted" error when it tries to allocated 15 bazillon bytes | |
554 | of space for the 15 bazillon byte table it is about to read. | |
555 | This function at least allows us to answer the quesion, "is the | |
556 | size reasonable?". | |
