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.

42 . {* A pointer to the target jump table. *}

45 . {* To avoid dragging too many header files into every file that
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. *}
54 . {* Is the file descriptor being cached? That is, can it be closed as
55 . needed, and re-opened when accessed later? *}

60 . BFD was opened. This is used to select which matching algorithm
61 . to use to choose the back end. *}

849 The initial motivation for, and use of, this routine is not
850 so we can get the exact size of the object the BFD applies to, since
851 that might not be generally possible (archive members for example).
852 It would be ideal if someone could eventually modify
853 it so that such results were guaranteed.
855 Instead, we want to ask questions like "is this NNN byte sized
856 object I'm about to try read from file offset YYY reasonable?"
857 As as example of where we might do this, some object formats
858 use string tables for which the first <<sizeof (long)>> bytes of the
859 table contain the size of the table itself, including the size bytes.
860 If an application tries to read what it thinks is one of these
861 string tables, without some way to validate the size, and for
862 some reason the size is wrong (byte swapping error, wrong location
863 for the string table, etc.), the only clue is likely to be a read
864 error when it tries to read the table, or a "virtual memory
865 exhausted" error when it tries to allocate 15 bazillon bytes
866 of space for the 15 bazillon byte table it is about to read.
