PGRAB_FILE(3PROC) Process Control Library Functions PGRAB_FILE(3PROC)

Pgrab_file
grab and inspect an ELF object

Process Control Library (libproc, -lproc)

#include <libproc.h>

struct ps_prochandle
Pgrab_file(const char *fname, int *perr);

The Pgrab_file() function creates a handle to the ELF object contained in file fname. 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) and Pcreate(3PROC) respectively. To inspect a core file use Pgrab_core(3PROC).

The perr 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.

An unexpected libelf(3LIB) failure occurred while processing the file named by fname.
The file named by fname is not a valid ELF file.
The file named by fname does not exist.
An unanticipated system error occurred while trying to grab the file fname and create the handle. The value of errno indicates the system failure.
