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

NAME         top

     acl_dup — duplicate an ACL

LIBRARY         top

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

SYNOPSIS         top

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

     acl_t
     acl_dup(acl_t acl);

DESCRIPTION         top

     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 call‐
     ing acl_free(3) with the (void*)acl_t returned by acl_dup() as an argu‐
     ment.

RETURN VALUE         top

     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 appropri‐
     ately.

ERRORS         top

     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         top

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