NAME

       acl_dup - Creates a duplicate copy of the ACL

LIBRARY

       Security Library (libpacl.a)

SYNOPSIS

       #include <sys/acl.h>
       acl_t acl_dup(	   acl_t acl_d);

PARAMETERS

       Specifies the working storage internal representation ACL to create a duplicate of.

DESCRIPTION

       NOTE:  This function is based on Draft 13 of the POSIX P1003.6 standard.

       The acl_dup() function creates a copy of the designated ACL.  Once created, this copy is independent of the original ACL.

RETURN VALUES

       Upon  successful  completion, the acl_dup() function returns a pointer to the new copy of the ACL.  Otherwise, a NULL value is returned and
       errno is set to indicate the error.

ERRORS

       If any of the following conditions occur, the acl_dup() function sets errno to the corresponding value:

       The acl_d parameter does not point to a valid ACL structure.  Unable to allocate memory for storing the duplicate ACL.

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 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.

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 appropri-
     ately.

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 con-
			straints.

STANDARDS

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