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

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.

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 constraints.

STANDARDS
     POSIX.1e is described in IEEE POSIX.1e draft 17.
