A BFD is has type <<bfd>>; objects of this type are the

cornerstone of any application using <<libbfd>>. References

though the BFD and to data in the BFD give the entire BFD

DESCRIPTION
|
|
|
|
|
This function calls the back end associated with the open

|
|
|
|
information attached to <<sec>> into the internal canonical
|
|
|
|
|
form. The table is placed into memory at <<loc>>, which has
|
|
|
|
|
been preallocated, usually by a call to
|
|
|
|
|
<<bfd_get_reloc_upper_bound>>.
|
|
|
|
|
|
|
|
|
|
The <<syms>> table is also needed for horrible internal magic
|
|
|
|
|
reasons.

The flag word contained a bit which was not applicable to the

FUNCTION
|
|
|
|
|
The bfd_get_size function
|

|

|
|
|
|
SYNOPSIS
|
|
|
|
|
long bfd_get_size(bfd *);
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
Return file size (as read from file system) for the file
|
|
|
|
|
associated with a bfd.
|
|
|
|
|
|
|
|
|
|
Note that the initial motivation for, and use of, this routine is not
|
|
|
|
|
so we can get the exact size of the object the bfd applies to, since
|
|
|
|
|
that might not be generally possible (archive members for example?).
|
|
|
|
|
Although it would be ideal if someone could eventually modify
|
|
|
|
|
it so that such results were guaranteed.
|
|
|
|
|
|
|
|
|
|
Instead, we want to ask questions like "is this NNN byte sized
|
|
|
|
|
object I'm about to try read from file offset YYY reasonable?"
|
|
|
|
|
As as example of where we might want to do this, some object formats
|
|
|
|
|
use string tables for which the first sizeof(long) bytes of the table
|
|
|
|
|
contain the size of the table itself, including the size bytes.
|
|
|
|
|
If an application tries to read what it thinks is one of these
|
|
|
|
|
string tables, without some way to validate the size, and for
|
|
|
|
|
some reason the size is wrong (byte swapping error, wrong location
|
|
|
|
|
for the string table, etc), the only clue is likely to be a read
|
|
|
|
|
error when it tries to read the table, or a "virtual memory
|
|
|
|
|
exhausted" error when it tries to allocated 15 bazillon bytes
|
|
|
|
|
of space for the 15 bazillon byte table it is about to read.
|
|
|
|
|
This function at least allows us to answer the quesion, "is the
|
|
|
|
|
size reasonable?".
