getppriv, setppriv - get or set a privilege set SYNOPSIS
#include <priv.h> int getppriv(priv_ptype_t which, priv_set_t *set); int setppriv(priv_op_t op, priv_ptype_t which, priv_set_t *set); DESCRIPTION
The getppriv() function returns the process privilege set specified by which in the set pointed to by set. The memory for set is allocated with priv_allocset() and freed with priv_freeset(). Both functions are documented on the priv_addset(3C) manual page. The setppriv() function sets or changes the process privilege set. The op argument specifies the operation and can be one of PRIV_OFF, PRIV_ON or PRIV_SET. The which argument specifies the name of the privilege set. The set argument specifies the set. If op is PRIV_OFF, the privileges in set are removed from the process privilege set specified by which. There are no restrictions on remov- ing privileges from process privileges sets, but the following apply: o Privileges removed from PRIV_PERMITTED are silently removed from PRIV_EFFECTIVE. o If privileges are removed from PRIV_LIMIT, they are not removed from the other sets until one of exec(2) functions has successfully completed. If op is PRIV_ON, the privileges in set are added to the process privilege set specified by which. The following operations are permitted: o Privileges in PRIV_PERMITTED can be added to PRIV_EFFECTIVE without restriction. o Privileges in PRIV_PERMITTED can be added to PRIV_INHERITABLE without restriction. o All operations that attempt to add privileges that are already present are permitted. If op is PRIV_SET, the privileges in set replace completely the process privilege set specified by which. PRIV_SET is implemented in terms of PRIV_OFF and PRIV_ON. The same restrictions apply. RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The getppriv() and setppriv() functions will fail if: EINVAL The value of op or which is out of range. EFAULT The set argument points to an illegal address. The setppriv() function will fail if: 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 which were not in PRIV_PERMITTED.
