acl_copy_ext(3)						       acl_copy_ext(3)

       acl_copy_ext  -	Copies the ACL from internal working space format to a
       contiguous, persistent form of the ACL

       #include <sys/acl.h>

       int acl_copy_ext(
	       void *buf_p,
	       acl_t acl_d,
	       ssize_t size );

       Security Library (libpacl.a)

       User space to copy the contiguous, persistent  for  of  the  ACL	 into.
       Specifies  the working storage, internal format ACL to copy.  Indicates
       the size of the buffer pointed to by buf_p.

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

       The  acl_copy_ext() function copies the contents of the ACL in internal
       working space format, pointed to by acl_d, into the buffer  pointed  to
       by  buf_p.  The ACL copied into the buffer is in contiguous, persistent
       formatxi and is not NULL terminated.

       Upon successful completion, the	acl_copy_ext()	function  returns  the
       size of the ACL copied.	Otherwise, a value of -1 is returned and errno
       is set to indicate the error.

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

       The  size  parameter  is	 zero or negative. The ACL referenced by acl_d
       contains one or more improperly formed ACL entries, or for  some	 other
       reason  can not be translated into contiguous format.  The size parame‐
       ter is greater than 0, but smaller than the ACL to be copied.
