getprivgrp(2) getprivgrp(2)

[E2BIG] The request would require assigning privileges to more than

PRIV_MAXGRPS

groups.

[EFAULT] mask points to an illegal address. The reliable detection of this error is implemen-

tation dependent.

[EINVAL] mask has bits set for one or more unknown privileges.

[EINVAL] grpid is out of range.

[EPERM] The caller is not a privileged user.

EXAMPLES

The following example prints out

PRIV_GLOBAL and the group IDs of the privilege groups to which the

user belongs:

#include <sys/types.h>

struct privgrp_map pgrplist[PRIV_MAXGRPS];

int i;

gid_t pgid;

getprivgrp (pgrplist);

for (i=0; i<PRIV_MAXGRPS; i++) {

if ((pgid = pgrplist[i].priv_groupno) != PRIV_NONE) {

if (pgid == PRIV_GLOBAL)

printf ("(PRIV_GLOBAL) ");

printf ("privilege group id = %d\n", pgid);

}
