  25         A BFD has type <<bfd>>; objects of this type are the
  26         cornerstone of any application using <<libbfd>>. Using BFD
  27         consists of making references though the BFD and to data in the BFD.
  28
  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.

 527         bfd_get_size
 528
 529 SYNOPSIS
 530         long bfd_get_size(bfd *abfd);
 531
 532 DESCRIPTION
 533         Return the file size (as read from file system) for the file
 534         associated with BFD @var{abfd}.
 535
 536         The initial motivation for, and use of, this routine is not
 537         so we can get the exact size of the object the BFD applies to, since
 538         that might not be generally possible (archive members for example).
 539         It would be ideal if someone could eventually modify
 540         it so that such results were guaranteed.
 541
 542         Instead, we want to ask questions like "is this NNN byte sized
 543         object I'm about to try read from file offset YYY reasonable?"
 544         As as example of where we might do this, some object formats
 545         use string tables for which the first <<sizeof(long)>> bytes of the
 546         table contain the size of the table itself, including the size bytes.
 547         If an application tries to read what it thinks is one of these
 548         string tables, without some way to validate the size, and for
 549         some reason the size is wrong (byte swapping error, wrong location
 550         for the string table, etc.), the only clue is likely to be a read
 551         error when it tries to read the table, or a "virtual memory
 552         exhausted" error when it tries to allocate 15 bazillon bytes
 553         of space for the 15 bazillon byte table it is about to read.
 554         This function at least allows us to answer the quesion, "is the
 555         size reasonable?".

 626         Convert, like <<strtoul>>, a numerical expression

 629         The expression is assumed to be unsigned (i.e. positive).
 630         If given a @var{base}, it is used as the base for conversion.
 631         A base of 0 causes the function to interpret the string
 632         in hex if a leading "0x" or "0X" is found, otherwise
 633         in octal if a leading zero is found, otherwise in decimal.
