LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO STANDARDS HISTORY AUTHORS

Standard C Library (libc, -lc)

#include <sys/types.h>

int
acl_get_perm_np(acl_permset_t permset_d, acl_perm_t perm);

The acl_get_perm_np() function is a non-portable function that checks if a permission is set in a permission set.

If the permission in perm is set in the permission set permset_d, a value of 1 is returned, otherwise a value of 0 is returned.

If any of the following conditions occur, the acl_get_perm_np() function will return a value of -1 and set global variable errno to the corresponding value:

[EINVAL]
	Argument perm does not contain a valid ACL permission or argument permset_d is not a valid ACL permset.

POSIX.1e is described in IEEE POSIX.1e draft 17.

POSIX.1e support was introduced in FreeBSD 4.0 . The acl_get_perm_np() function was added in FreeBSD 5.0 .

The acl_get_perm_np() function was written by Chris D. Faulhaber <Mt jedgar@fxp.org>.
