NAME

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

LIBRARY

       Security Library (libpacl.a)

SYNOPSIS

       #include <sys/acl.h>
       int acl_copy_ext(      void *buf_p,	acl_t acl_d,	  ssize_t size);

PARAMETERS

       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.

DESCRIPTION

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

       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.

RETURN VALUES

       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.

ERRORS

       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  con-
       tiguous format.

       The size parameter is greater than 0, but smaller than the ACL to be copied.

NAME

     acl_copy_ext -- copy an ACL from internal to external representation

LIBRARY

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

SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     ssize_t
     acl_copy_ext(void *buf_p, acl_t acl, ssize_t size);

DESCRIPTION

     The acl_copy_ext() function copies the ACL pointed to by acl from system-managed space to the user managed space pointed to by buf_p.  The
     size parameter represents the size in bytes of the buffer pointed to by buf_p.  The format of the ACL placed in the buffer pointed to by
     buf_p is a contiguous, persistent data item, the format of which is unspecified.  It is the responsibility of the invoker to allocate an area
     large enough to hold the copied ACL. The size of the exportable, contiguous, persistent form of the ACL may be obtained by invoking the
     acl_size() function.

     Any ACL entry descriptors that refer to an entry in the ACL referenced by acl continue to refer to those entries. Any existing ACL pointers
     that refer to the ACL referenced by acl continue to refer to the ACL.

RETURN VALUE

     Upon successful completion, this function returns the number of bytes placed in the buffer pointed to by buf_p.  Otherwise, a value of
     (ssize_t)-1 is returned and errno is set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_copy_ext() function returns a value of (ssize_t)-1 and sets errno to the corresponding
     value:

     [EINVAL]		The size parameter is zero or negative.

			The argument acl is not a valid pointer to an ACL.

			The ACL referenced by acl contains one or more improperly formed ACL entries, or for some other reason cannot be trans-
			lated into the external form of an ACL.

     [ERANGE]		The size parameter is greater than zero but smaller than the length of the contiguous, persistent form of the ACL.

STANDARDS
