PEXECNAME(3PROC) Process Control Library Functions PEXECNAME(3PROC)
NAME
Pexecname - obtain full path to process executable
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> char * Pexecname(
struct ps_prochandle *P,
char *buf,
size_t buflen);
DESCRIPTION
The
Pexecname() function attempts to determine the full path to the
process executable referred to by the handle
P.
If found,
buf will be filled in with the full path for up to
buflen bytes, including the null terminator.
For a handle grabbed with
Pgrab_file(3PROC), the executable refers to
the path of the file itself. For a core file, the system attempts to
determine the original path of the executable and return that.
RETURN VALUES
Upon successful completion, the
Pexecname() function returns the value
of
buf, and up to
buflen bytes of
buf are filled in with a null-
terminated path. Otherwise, NULL is returned.
