ACL_DUP(3)						   BSD Library Functions Manual 						ACL_DUP(3)

NAME

     acl_dup -- duplicate an ACL

LIBRARY

     Linux Access Control Lists library (libacl, -lacl).

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 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 returned by acl_dup() as an argument.

RETURN VALUE

     Upon successful completion, this function returns a pointer to the working storage.  Otherwise, a value of (acl_t)NULL is returned, and errno
     is set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_dup() function returns a value of (acl_t)NULL and sets errno to the corresponding value:

     [EINVAL]		The argument acl is not a valid pointer to an ACL.

     [ENOMEM]		The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)

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 management con-
			straints.

SEE ALSO

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 continues.
