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 mem-
     ory, 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)
