ACLDUP(3) BSD Library Functions Manual ACLDUP(3)

NAME
     aacclldduupp - duplicate an ACL

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>
     ##iinncclluuddee <>

     aclt
     aacclldduupp(aclt acl);

DESCRIPTION
     The aacclldduupp() 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
     aclfree(3) with the (void*)aclt 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 (aclt)NULL shall be returned, and
     errno shall be set to indicate the error.

EERRRROORRSS
     If any of the following conditions occur, the aacclliinniitt() function shall
     return a value of (aclt)NULL and set errno to the corresponding value:

     [EINVAL]           Argument acl does not point to a valid ACL.

     [ENOMEM]           The aclt to be returned requires more memory than is
                        allowed by the hardware or system-imposed memory man-
                        agement constraints.
