Manual Pages  — ACL_STRIP_NP


acl_strip_np – strip extended entries from an ACL



Standard C Library (libc, -lc)


#include <sys/types.h>
#include <sys/acl.h>

acl_strip_np(const acl_t acl, int recalculate_mask);


The acl_strip_np() function returns a pointer to a trivial ACL computed from the ACL pointed to by the argument acl.

This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with the (void*)acl_t as an argument.

Any existing ACL pointers that refer to the ACL referred to by acl shall continue to refer to the ACL.


Upon successful completion, this function shall return a pointer to the newly allocated ACL. Otherwise, a value of (acl_t)NULL shall be returned, and errno shall be set to indicate the error.


If any of the following conditions occur, the acl_init() function shall return a value of (acl_t)NULL and set errno to the corresponding value:
  Argument acl does not point to a valid ACL.
  The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.


acl(3), acl_is_trivial_np(3), posix1e(3)


POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the FreeBSD POSIX.1e implementation page for more information.


POSIX.1e support was introduced in FreeBSD 4.0 . The acl_strip_np() function was added in FreeBSD 8.0 .

An ASCII character walks into a bar and orders a double. "Having a bad day?" asks the barman. "Yeah, I have a parity error," replies the ASCII character. The barman says, "Yeah, I thought you looked a bit off."
