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. | |

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

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

1003 | DESCRIPTION | |
1004 | Convert, like <<strtoul>>, a numerical expression | |
1005 | @var{string} into a <<bfd_vma>> integer, and return that integer. | |
1006 | (Though without as many bells and whistles as <<strtoul>>.) | |
1007 | The expression is assumed to be unsigned (i.e., positive). | |
1008 | If given a @var{base}, it is used as the base for conversion. | |
1009 | A base of 0 causes the function to interpret the string | |
1010 | in hex if a leading "0x" or "0X" is found, otherwise | |
1011 | in octal if a leading zero is found, otherwise in decimal. | |
1012 | ||
