NAME
       tt_message_arg_bval -- retrieve the byte-array value of a message argu-
       ment

SYNOPSIS
       #include	<Tt/tt_c.h>
       Tt_status tt_message_arg_bval(
       Tt_message m,
       int n,
       unsigned	char **value,
       int *len);

DESCRIPTION
       The tt_message_arg_bval function	retrieves the byte-array value of  the
       nth 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  re-
       trieved.	  The  first argument is numbered zero.	 The value argument is
       the address of a	character pointer to which the ToolTalk	service	is  to
       point a string that contains the	contents of the	argument.  The len ar-
       gument is the address of	an integer to which the	ToolTalk service is to
       set the length of the value in bytes.

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

       TT_OK	 The operation completed successfully.

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

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

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