NAME
     tt_message_arg_xval_set - serialize and  set  data	 into  an
     existing message argument

SYNOPSIS
     #include <Tt/tt_c.h>

     Tt_status tt_message_arg_xval_set(Tt_message m,
				       int n,
				       xdrproc_t xdr_proc,
				       void *value);

DESCRIPTION
     The tt_message_arg_xval_set() function serializes	and  sets
     data into an existing message argument.

     The m argument is the opaque handle for the message involved
     in	 this  operation.   The	 n  argument is	the number of the
     argument to be changed.   The  first  argument  is	 numbered
     zero.	   The	     xdr_proc	    argument	   causes
     tt_message_arg_xval_set() to serialize the	data  pointed  to
     by	 value	and  store  it	as a byte string value of the nth
     argument of the message.  The value argument is the data  to
     be	serialized.

RETURN VALUE
     Upon successful  completion,  the	tt_message_arg_xval_set()
     function  returns	the status of the operation as one of the
     following Tt_status values:

	TT_OK	The operation completed	successfully.

	TT_ERR_MODE
		The specified Tt_mode is invalid.

	TT_ERR_NOMP
		The ttsession(1) process is not	running	 and  the
		ToolTalk service cannot	restart	it.

	TT_ERR_POINTER
		The pointer passed does	not point to an	object of
		the correct type for this operation.

	TT_ERR_NUM
		The integer value  passed  was	invalid	 (out  of
		range).

	TT_ERR_XDR
		The XDR	procedure failed on the	 given	data,  or
		evaluated to a zero-length expression.
