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

       On  success, this function returns a pointer to the working storage.  On error, a value of (acl_t)NULL is
       returned, and errno is set appropriately.

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 constraints.

STANDARDS

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