NAME    [Toc]    [Back]

     acl_dup -- duplicate an ACL

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

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

     acl_dup(acl_t acl);

DESCRIPTION    [Toc]    [Back]

     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.


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

RETURN VALUES    [Toc]    [Back]

     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    [Toc]    [Back]

     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

SEE ALSO    [Toc]    [Back]

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

STANDARDS    [Toc]    [Back]

     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

HISTORY    [Toc]    [Back]

     POSIX.1e support was introduced in FreeBSD 4.0, and development continues.
