ACL_DUP(3)               Library Functions Manual             ACL_DUP(3)

ИМЯ

       acl_dup — duplicate an ACL

БИБЛИОТЕКА

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

СИНТАКСИС

       <sys/types.h> <sys/acl.h> acl_t acl_dup(acl_t acl)

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ ВОЗВРАТА

       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.

ОШИБКИ

       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.
