priv_set(3C)                                               Standard C Library Functions                                               priv_set(3C)

NAME

       priv_set, priv_ineffect - change privilege sets and check whether privileges are set

SYNOPSIS

       #include <priv.h>

       int priv_set(priv_op_t op, priv_ptype_t  which, ...);

       boolean_t priv_ineffect(const char *priv);

DESCRIPTION

       The priv_set() function is a convenient wrapper for the setppriv(2) function. It takes three or more arguments. The operation argument, op,
       can be one of PRIV_OFF, PRIV_ON or PRIV_SET. The which argument is the name of the privilege set to change. The third argument is a list of
       zero  or  more  privilege  names  terminated  with a null pointer. If which is the special pseudo set PRIV_ALLSETS, the operation should be
       applied to all privilege sets.

       The specified privileges are converted to a binary privilege set and setppriv() is called with the  same  op  and  which  arguments.   When
       called with PRIV_ALLSETS as the value for the which argument, setppriv() is called for each set in turn, aborting on the first failed call.

       The  priv_ineffect()  function is a conventient wrapper for the getppriv(2) function. The priv argument specifies the name of the privilege
       for which this function checks its presence in the effective set.

RETURN VALUES

       Upon successful completion, priv_set() return 0. Otherwise, -1  is returned and errno is set to indicate the error.

       If priv is a valid privilege that is a member of the effective set, priv_ineffect() returns B_TRUE. Otherwise, it returns B_FALSE and  sets
       errno to incicate the error.

ERRORS

       The priv_set() function will fail if:

       EINVAL          The value of op or which is out of range.

       ENOMEM          Insufficient memory was allocated.

       EPERM           The application attempted to add privileges to PRIV_LIMIT or PRIV_PERMITTED, or the application attempted to add privileges
                       to PRIV_INHERITABLE or PRIV_EFFECTIVE that were not in PRIV_PERMITTED.

       The priv_ineffect() function will fail if:

       EINVAL          The privilege specified by priv is invalid.

       ENOMEM          Insufficient memory was allocated.
