Psetpriv —
set process privileges
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
Psetpriv(
struct
ps_prochandle *P,
prpriv_t *pprv);
The
Psetpriv() function updates the
privileges of the process handle
P to the set
described by
pprv. The updated privilege set
has restrictions on what it may change for a process which are documented in
the
PCSPRIV section of
proc(4). In addition, the definition of the
prpriv_t structure is described in
proc(4).
The current privilege set for the process may be obtained through a call to
Ppriv(3PROC).
Note, the privilege set may only be updated for active processes. Process
handles which correspond to core files, zombie processes, and files, may not
have their privilege sets updated.
Upon successful completion, the
Psetpriv()
function returns
0 and updates the privilege sets
of the process. Otherwise,
-1 is returned and
errno is set to indicate the error.
For a full list of possible errors see the
DIAGNOSTICS section in
proc(4).
The
Psetpriv() function will fail if:
-
-
EBADF- P doesn't refer to an active process, but
a core file, zombie, or a file.
