NAME
acl_strip_np —
strip extended entries from an
ACL
LIBRARY
library “libc”
SYNOPSIS
#include
<sys/types.h>
#include <sys/acl.h>
acl_t
acl_strip_np(const
acl_t acl, int
recalculate_mask);
DESCRIPTION
Theacl_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.
RETURN VALUES
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.
ERRORS
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 management constraints.
