SYNOPSIS

bfd *bfd_fdopenr(CONST char *filename, CONST char *target, int fd);
|
||
|
||
DESCRIPTION
|

<<bfd_fdopenr>> is to <<bfd_fopenr>> much like <<fdopen>> is to <<fopen>>.
|
||
It opens a BFD on a file already described by the @var{fd}
|
||
supplied.
|
||
|
||
When the file is later <<bfd_close>>d, the file descriptor will be closed.
|
||
|
||
If the caller desires that this file descriptor be cached by BFD
|
||
(opened as needed, closed as needed to free descriptors for
|
||
other opens), with the supplied @var{fd} used as an initial
|
||
file descriptor (but subject to closure at any time), call
|
||
bfd_set_cacheable(bfd, 1) on the returned BFD. The default is to
|
||
assume no cacheing; the file descriptor will remain open until
|
||
<<bfd_close>>, and will not be affected by BFD operations on other
|
||
files.
|
||
|
||
Possible errors are <<no_memory>>, <<invalid_target>> and <<system_call_error>>.
