ACL_STRIP_NP(3)         NetBSD Library Functions Manual        ACL_STRIP_NP(3)


NAME

     acl_strip_np -- strip extended entries from an ACL


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

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

     acl_t
     acl_strip_np(const acl_t acl, int recalculate_mask);


DESCRIPTION

     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.


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 man-
                        agement constraints.

STANDARDS

     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.


HISTORY

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