ACL_STRIP_NP(3) BSD Library Functions Manual ACL_STRIP_NP(3)NAMEacl_strip_np — strip exteneded entries from an ACL
Standard C Library (libc, -lc)
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:
[EINVAL] Argument acl does not point to a valid ACL.
[ENOMEM] The acl_t to be returned requires more memory than is
allowed by the hardware or system-imposed memory man‐

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