Psetcred —
set process credentials
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
Psetcred(
struct
ps_prochandle *P,
const prcred_t
*credp);
The
Psetcred() function updates the
credentials of the process handle
P to the
values set in
credp.
credp must be fully initialized. The
definition of the
prcred_t structure may be found
in
proc(4).
Note, the credentials may only be updated for an active process. If the process
handle refers to a zombie process, core file, or a file, then
Psetcred() will fail.
Upon successful completion, the
Psetcred()
function returns
0 and updates the credentials of
the process
P. Otherwise,
-1 is returned.
