PGRAB_FILE(3PROC) Process Control Library Functions PGRAB_FILE(3PROC)
- grab and inspect an ELF object
Process Control Library (libproc, -lproc)
SYNOPSIS #include <libproc.h> struct ps_prochandle Pgrab_file
(const char *fname
, int *perr
() function creates a handle to the ELF object contained in
. This handle is considered an idle
handle, it allows one to
inspect aspects of the ELF contents present in the handle, for example
obtaining CTF information and looking up symbols.
There is no running state associated with this handle nor can there be. If
one intends to control a running process or create a process, see Pgrab(3PROC)
respectively. To inspect a core file use Pgrab_core(3PROC)
argument must be a non-NULL pointer which will store a more
detailed error in the event that Pgrab_file
() fails. A human-readable form
of the error can be obtained with Pgrab_error(3PROC)
When finished with the returned handle, Prelease(3PROC)
must be called to
clean up resources associated with it.
Upon successful completion, the Pgrab_file
() function returns a control
handle to the process. Otherwise, NULL is returned and perr
is filled in
with an error code.
G_ELF An unexpected libelf(3LIB)
failure occurred while
processing the file named by fname
G_FORMAT The file named by fname
is not a valid ELF file.
G_NOEXEC The file named by fname
does not exist.
G_STRANGE An unanticipated system error occurred while
trying to grab the file fname
and create the
handle. The value of errno
indicates the system
