Pexecname —
obtain full path to process executable
Process Control Library (libproc, -lproc)
#include
<libproc.h>
char *
Pexecname(
struct
ps_prochandle *P,
char *buf,
size_t buflen);
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.
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.
