#include <priv.h> int priv_addset(priv_set_t *sp, const char *priv); priv_set_t *priv_allocset(void); void priv_copyset(const priv_set_t *src, priv_set_t *dst); int priv_delset(priv_set_t *sp, const char *priv); void priv_emptyset(priv_set_t *sp); void priv_fillset(priv_set_t *sp); void priv_freeset(priv_set_t *sp); void priv_intersect(const priv_set_t *src, priv_set_t *dst); void priv_inverse(priv_set_t *sp); boolean_t priv_isemptyset(const priv_set_t *sp); boolean_t priv_isequalset(const priv_set_t *src, const priv_set_t *dst); boolean_t priv_isfullset(const priv_set_t *sp); boolean_t priv_ismember(const priv_set_t *sp, const char *priv); boolean_t priv_issubset(const priv_set_t *src, const priv_set_t *dst); void priv_union(const priv_set_t *src, priv_set_t *dst); The sp, src, and dst arguments point to privilege sets. The priv argument points to a named privilege. The priv_addset() function adds the named privilege priv to sp. The priv_allocset() function allocates sufficient memory to contain a privilege set. The value of the returned privilege set is indetermi- nate. The function returns NULL and sets errno when it fails to allocate memory. The priv_copyset() function copies the set src to dst. The priv_delset() function removes the named privilege priv from sp. The priv_emptyset() function clears all privileges from sp. The priv_fillset() function asserts all privileges in sp, including the privileges not currently defined in the system. The priv_freeset() function frees the storage allocated by priv_allocset(). The priv_intersect() function intersects src with dst and places the results in dst. The priv_inverse() function inverts the privilege set given as argument in place. The priv_isemptyset() function checks whether the argument is an empty set. The priv_isequalset() function checks whether the privilege set src is equal to dst. The priv_isfullset() function checks whether the argument is a full set. A full set is a set with all bits set, regardless of whether the privilege is currently defined in the system. The priv_ismember() function checks whether the named privilege priv is a member of sp. The priv_issubset() function checks whether src is a subset of dst. The priv_union() function takes the union of src and dst and places the result in dst. Upon successful completion, priv_allocset() returns a pointer to an opaque data structure. It returns NULL if memory allocation fails and sets errno to indicate the error. Upon successful completion, priv_isemptyset(), priv_isfullset(), priv_isequalset(), priv_issubset(), and priv_ismember() return B_TRUE. Otherwise, they return B_FALSE. Upon successful completion, priv_delset() and priv_addset() return 0. Otherwise, they return -1 and set errno to indicate the error. The priv_allocset() function will fail if: ENOMEM The physical limits of the system are exceeded by the memory allocation needed to hold a privilege set. EAGAIN There is insufficient memory for allocation to hold a privilege set. The application can try again later. The priv_delset() and priv_addset() functions will fail if: EINVAL The privilege argument is not a valid privilege name. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ setppriv(2), malloc(3C), priv_str_to_set(3C), attributes(5), privileges(5) The functions that compare sets operate on all bits of the set, regardless of whether the specific privileges are currently defined in the system. 28 Jan 2005 priv_addset(3C)
