@strong{Description}@*
|
|
Open the file @var{filename} with the target @var{target}.
|
|
Return a pointer to the created BFD. If @var{fd} is not -1,
|
|
then @code{fdopen} is used to open the file; otherwise, @code{fopen}
|
|
is used. @var{mode} is passed directly to @code{fopen} or
|
|
@code{fdopen}.
|
|
|
|
Calls @code{bfd_find_target}, so @var{target} is interpreted as by
|
|
that function.
|
|
|
|
The new BFD is marked as cacheable iff @var{fd} is -1.
|
|
|
|
If @code{NULL} is returned then an error has occured. Possible errors
|
|
are @code{bfd_error_no_memory}, @code{bfd_error_invalid_target} or

@code{system_call} error.
|
|
|
|
On error, @var{fd} is always closed.

|
|
@strong{Description}@*
|
|
@code{bfd_fdopenr} is to @code{bfd_fopenr} much like @code{fdopen} is to
|
|
@code{fopen}. It opens a BFD on a file already described by the
|
|
@var{fd} supplied.
|
|
|
|
When the file is later @code{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 caching; the file descriptor will remain open
|
|
until @code{bfd_close}, and will not be affected by BFD operations
|
|
on other files.
|
|
|
|
Possible errors are @code{bfd_error_no_memory},
|
|
@code{bfd_error_invalid_target} and @code{bfd_error_system_call}.
|
|
|
|
On error, @var{fd} is closed.

@end example
|
|
@strong{Description}@*
|
|
Create and return a BFD backed by a read-only @var{stream}.
|
|
The @var{stream} is created using @var{open_func}, accessed using
|
|
@var{pread_func} and destroyed using @var{close_func}.
|
|
|
|
Calls @code{bfd_find_target}, so @var{target} is interpreted as by
|
|
that function.
|
|
|
|
Calls @var{open_func} (which can call @code{bfd_zalloc} and
|
|
@code{bfd_get_filename}) to obtain the read-only stream backing
|
|
the BFD. @var{open_func} either succeeds returning the
|
|
non-@code{NULL} @var{stream}, or fails returning @code{NULL}
|
|
(setting @code{bfd_error}).
|
|
|
|
Calls @var{pread_func} to request @var{nbytes} of data from
|
|
@var{stream} starting at @var{offset} (e.g., via a call to
|
|
@code{bfd_read}). @var{pread_func} either succeeds returning the
|
|
number of bytes read (which can be less than @var{nbytes} when
|
|
end-of-file), or fails returning -1 (setting @code{bfd_error}).
|
|
|
|
Calls @var{close_func} when the BFD is later closed using
|
|
@code{bfd_close}. @var{close_func} either succeeds returning 0, or
|
|
fails returning -1 (setting @code{bfd_error}).
|
|
|
|
Calls @var{stat_func} to fill in a stat structure for bfd_stat,
|
|
bfd_get_size, and bfd_get_mtime calls. @var{stat_func} returns 0
|
|
on success, or returns -1 on failure (setting @code{bfd_error}).
|
|
|
|
If @code{bfd_openr_iovec} returns @code{NULL} then an error has
|
|
occurred. Possible errors are @code{bfd_error_no_memory},

@code{bfd_error_invalid_target} and @code{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 @code{chmod} is called

All memory attached to the BFD is released.

Close a BFD. Differs from @code{bfd_close} since it does not

(bfd *abfd, const char *filename);
|

@end example
|
|
@strong{Description}@*
|
|
Takes a @var{BFD} and adds a .gnu_debuglink section to it. The
|
|
section is sized to be big enough to contain a link to the specified
|
|
@var{filename}.
|
|
|
|
@strong{Returns}@*
|
|
A pointer to the new section is returned if all is ok. Otherwise
|
|
@code{NULL} is returned and bfd_error is set.

@strong{Description}@*
|
|
Takes a @var{BFD} and containing a .gnu_debuglink section @var{SECT}
|
|
and fills in the contents of the section to contain a link to the
|
|
specified @var{filename}. The filename should be relative to the
|
|
current directory.
|
|
|
|
@strong{Returns}@*
|
|
@code{TRUE} is returned if all is ok. Otherwise @code{FALSE} is returned

and bfd_error is set.

@example

struct bfd_build_id * get_build_id (bfd *abfd);
|

@end example
|
|
@strong{Description}@*
|
|
Finds the build-id associated with @var{abfd}. If the build-id is
|
|
extracted from the note section then a build-id structure is built
|
|
for it, using memory allocated to @var{abfd}, and this is then
|
|
attached to the @var{abfd}.
|
|
|
|
@strong{Returns}@*
|
|
Returns a pointer to the build-id structure if a build-id could be
|
|
found. If no build-id is found NULL is returned and error code is
|
|
set.

|
|
char * get_build_id_name (bfd *abfd, void *build_id_out_p)
|
|
@end example
|
|
@strong{Description}@*
|
|
Searches @var{abfd} for a build-id, and then constructs a pathname
|
|
from it. The path is computed as .build-id/NN/NN+NN.debug where
|
|
NNNN+NN is the build-id value as a hexadecimal string.
|
|
|
|
@strong{Returns}@*
|
|
Returns the constructed filename or NULL upon error.
|
|
It is the caller's responsibility to free the memory used to hold the
|
|
filename.
|
|
If a filename is returned then the @var{build_id_out_p}
|
|
parameter (which points to a @code{struct bfd_build_id}
|
|
pointer) is set to a pointer to the build_id structure.

@end example
|
|
@strong{Description}@*
|
|
Checks to see if @var{name} is a readable file and if its build-id
|
|
matches @var{buildid}.
|
|
|
|
@strong{Returns}@*
|
|
Returns TRUE if the file exists, is readable, and contains a
|
|
build-id which matches the build-id pointed at by
|
|
@var{build_id_p} (which is really a @code{struct bfd_build_id **}).

@example
|
|
char *bfd_follow_build_id_debuglink (bfd *abfd, const char *dir);
|
|
@end example
|
|
@strong{Description}@*
|
|
Takes @var{abfd} and searches it for a .note.gnu.build-id section.
|
|
If this section is found, it extracts the value of the NT_GNU_BUILD_ID
|
|
note, which should be a hexadecimal value @var{NNNN+NN} (for
|
|
32+ hex digits). It then searches the filesystem for a file named
|
|
@var{.build-id/NN/NN+NN.debug} in a set of standard locations,
|
|
including the directory tree rooted at @var{dir}. The filename
|
|
of the first matching file to be found is returned. A matching
|
|
file should contain a .note.gnu.build-id section with the same
|
|
@var{NNNN+NN} note as @var{abfd}, although this check is currently
|
|
not implemented.
|
|
|
|
If @var{dir} is NULL, the search will take place starting at
|
|
the current directory.
|
|
|
|
@strong{Returns}@*
|
|
@code{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.
