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.
See LOCKING in libproc(3LIB).
