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.

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? *}

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