|
|
|
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. |
|
|
|
supplied. |
|
|
|
|
|
|
|
When the file is later bfd_closed, 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), set |
|
|
|
bfd->cacheable nonzero in 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. |
