|
|

|
|
DESCRIPTION
|
|
|
|
|
Open the file @var{filename} (using <<fopen>>) with the target
|
|
|
|
|
@var{target}. Return a pointer to the created BFD.
|
|
|
|
|
|
|
|
|
|
Calls <<bfd_find_target>>, so @var{target} is interpreted as by
|
|
|
|
|
that function.
|
|
|
|
|
|
|
|
|
|
If <<NULL>> is returned then an error has occured. Possible errors
|
2002-10-06 11:03:06 +02:00
|
|
|
|
are <<bfd_error_no_memory>>, <<bfd_error_invalid_target>> or
|
|
|
|
|
<<system_call>> error.

|
DESCRIPTION
|
2002-10-06 11:03:06 +02:00
|
|
|
|
<<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 <<bfd_error_no_memory>>,
|
|
|
|
|
<<bfd_error_invalid_target>> and <<bfd_error_system_call>>.

Close a BFD. If the BFD was open for writing, then pending

operations are completed and the file written out and closed.

If the created file is executable, then <<chmod>> is called

The file descriptor associated with the BFD is closed (even

DESCRIPTION

2002-10-06 11:03:06 +02:00
|
|
|
|
Close a BFD. Differs from <<bfd_close>> since it does not
|
|
|
|
|
complete any pending operations. This routine would be used
|
|
|
|
|
if the application had just used BFD for swapping and didn't
|
|
|
|
|
want to use any of the writing code.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
If the created file is executable, then <<chmod>> is called
|
|
|
|
|
to mark it as such.
|
|
|
|
|
|
|
|
|
|
All memory attached to the BFD is released.

RETURNS

|
|

|
<<TRUE>> is returned if all is ok, otherwise <<FALSE>>.

bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

GNU Extension: separate debug-info files

The idea here is that a special section called .gnu_debuglink might be
|
|
|
|
|
embedded in a binary file, which indicates that some *other* file
|
|
|
|
|
contains the real debugging information. This special section contains a
|
|
|
|
|
filename and CRC32 checksum, which we read and resolve to another file,
|
|
|
|
|
if it exists.
|
|
|
|
|
|
|
|
|
|
This facilitates "optional" provision of debugging information, without
|
|
|
|
|
having to provide two complete copies of every binary object (with and
|
|
|
|
|
without debug symbols).

DESCRIPTION
|
|
|
|
|
Searches @var{abfd} for a reference to separate debugging
|
|
|
|
|
information, scans various locations in the filesystem, including
|
|
|
|
|
the file tree rooted at @var{debug_file_directory}, and returns a
|
|
|
|
|
filename of such debugging information if the file is found and has
|
|
|
|
|
matching CRC32. Returns NULL if no reference to debugging file
|
|
|
|
|
exists, or file cannot be found.

SYNOPSIS

|
char * bfd_follow_gnu_debuglink(bfd *abfd, const char *dir);
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Takes a BFD and searches it for a .gnu_debuglink section. If this
|
|
|
|
|
section is found, examines the section for the name and checksum of
|
|
|
|
|
a '.debug' file containing auxiliary debugging
|
|
|
|
|
information. Searches filesystem for .debug file in some standard
|
|
|
|
|
locations, including the directory tree rooted at @var{dir}, and if
|
|
|
|
|
found returns the full filename. If @var{dir} is NULL, will search
|
|
|
|
|
default path configured into libbfd at build time.
|
|
|
|
|
|
|
|
|
|
RETURNS
|
|
|
|
|
<<NULL>> on any errors or failure to locate the .debug file,
|
|
|
|
|
otherwise a pointer to a heap-allocated string containing the
|
|
|
|
|
filename. The caller is responsible for freeing this string.
