ACL_DUP(3)	       FreeBSD Library Functions Manual		    ACL_DUP(3)

NAME
     acl_dup --	duplicate an ACL

LIBRARY
     Standard C	Library	(libc, -lc)

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

     acl_t
     acl_dup(acl_t acl);

DESCRIPTION
     The acl_dup() function returns a pointer to a copy	of 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.

IMPLEMENTATION NOTES
     FreeBSD's support for POSIX.1e interfaces and features is still under
     development at this time.

RETURN VALUES
     Upon successful completion, this function shall return a pointer to the
     duplicate 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.

SEE ALSO
     acl(3), acl_free(3), acl_get(3), posix1e(3)

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, and development contin-
     ues.
