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

46 . are cast when used, are "FILE *" and "time_t". The iostream
47 . is the result of an fopen on the filename. However, if the
48 . BFD_IN_MEMORY flag is set, then iostream is actually a pointer
49 . to a bfd_in_memory struct. *}

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

724 The initial motivation for, and use of, this routine is not
725 so we can get the exact size of the object the BFD applies to, since
726 that might not be generally possible (archive members for example).
727 It would be ideal if someone could eventually modify
728 it so that such results were guaranteed.
730 Instead, we want to ask questions like "is this NNN byte sized
731 object I'm about to try read from file offset YYY reasonable?"
732 As as example of where we might do this, some object formats
733 use string tables for which the first <<sizeof(long)>> bytes of the
734 table contain the size of the table itself, including the size bytes.
735 If an application tries to read what it thinks is one of these
736 string tables, without some way to validate the size, and for
737 some reason the size is wrong (byte swapping error, wrong location
738 for the string table, etc.), the only clue is likely to be a read
739 error when it tries to read the table, or a "virtual memory
740 exhausted" error when it tries to allocate 15 bazillon bytes
741 of space for the 15 bazillon byte table it is about to read.
