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

Error reporting

|
|
|

|
|
Most BFD functions return nonzero on success (check their
|
|
|
|
|
individual documentation for precise semantics). On an error,
|
|
|
|
|
they call <<bfd_set_error>> to set an error condition that callers
|
|
|
|
|
can check by calling <<bfd_get_error>>.
|
|
|
|
|
If that returns <<bfd_error_system_call>>, then check
|
|
|
|
|
<<errno>>.
|
|
|
|
|
|
|
|
|
|
The easiest way to report a BFD error to the user is to
|
|
|
|
|
use <<bfd_perror>>.

BFD error handler

Some BFD functions want to print messages describing the

problem. They call a BFD error handler function. This

|
|
|
|
function may be overriden by the program.
|

|
|
|
|
The BFD error handler acts like printf.

SYNOPSIS

|
|
|
Set the flag word in the BFD @var{abfd} to the value @var{flags}.
|
|
|
|
|
|
|
|
|
|
Possible errors are:
|
|
|
|
|
o <<bfd_error_wrong_format>> - The target bfd was not of object format.
|
|
|
|
|
o <<bfd_error_invalid_operation>> - The target bfd was open for reading.
|
|
|
|
|
o <<bfd_error_invalid_operation>> -
|
|
|
|
|
The flag word contained a bit which was not applicable to the
|
|
|
|
|
type of file. E.g., an attempt was made to set the <<D_PAGED>> bit
|
|
|
|
|
on a BFD format which does not support demand paging.

long bfd_get_size(bfd *abfd);
|

|
DESCRIPTION
|
|
|
|
|
Return the file size (as read from file system) for the file
|
|
|
|
|
associated with BFD @var{abfd}.
|
|
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
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 do this, some object formats
|
2000-11-21 03:24:32 +01:00
|
|
|
|
use string tables for which the first <<sizeof (long)>> bytes of the
|
1999-05-03 09:29:11 +02:00
|
|
|
|
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 allocate 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?".

SYNOPSIS
|
2001-08-09 11:09:03 +02:00

|
|
|
bfd_vma bfd_scan_vma(const char *string, const char **end, int base);

|
|
|
|
DESCRIPTION
|
|
|
|
|
Convert, like <<strtoul>>, a numerical expression
|
|
|
|
|
@var{string} into a <<bfd_vma>> integer, and return that integer.
|
|
|
|
|
(Though without as many bells and whistles as <<strtoul>>.)
|
|
|
|
|
The expression is assumed to be unsigned (i.e., positive).
|
|
|
|
|
If given a @var{base}, it is used as the base for conversion.
|
|
|
|
|
A base of 0 causes the function to interpret the string
|
|
|
|
|
in hex if a leading "0x" or "0X" is found, otherwise
|
|
|
|
|
in octal if a leading zero is found, otherwise in decimal.
|
|
|
|
|
|
2002-02-15 01:20:17 +01:00
|
|
|
|
If the value would overflow, the maximum <<bfd_vma>> value is
|
|
|
|
|
returned.

SYNOPSIS

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
When more than one machine code number is available for the
|
|
|
|
|
same machine type, this function can be used to switch between
|
|
|
|
|
the preferred one (index == 0) and any others. Currently,
|
|
|
|
|
only ELF supports this feature, with up to two alternate
|
|
|
|
|
machine codes.
