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.
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.

46 . includes `<<bfd.h>>', IOSTREAM has been declared as a "char
47 . *", and MTIME as a "long". Their correct types, to which they
48 . are cast when used, are "FILE *" and "time_t". The iostream
49 . is the result of an fopen on the filename. However, if the
50 . BFD_IN_MEMORY flag is set, then iostream is actually a pointer
51 . to a bfd_in_memory struct. *}

55 . needed, and re-opened when accessed later? *}

866 The initial motivation for, and use of, this routine is not
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.
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
875 use string tables for which the first <<sizeof (long)>> bytes of the
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.

1004 @var{string} into a <<bfd_vma>> integer, and return that integer.
1005 (Though without as many bells and whistles as <<strtoul>>.)

1008 A base of 0 causes the function to interpret the string
1009 in hex if a leading "0x" or "0X" is found, otherwise
1010 in octal if a leading zero is found, otherwise in decimal.
