tt_message_context_bval(library	call)	 tt_message_context_bval(library call)

NAME
       tt_message_context_bval	-- retrieve the	byte-array value and length of
       a message's context

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

DESCRIPTION
       The tt_message_context_bval function retrieves the byte-array value and
       length of a message's context.

       If  there  is no	context	slot associated	with slotname, tt_message_con-
       text_bval returns zero in slotname and zero in len.

       The m argument is the opaque handle for the message  involved  in  this
       operation.   The	 slotname  argument describes the context of this mes-
       sage.  The value	argument points	to the location	to return  the	value.
       The len argument	is the length of the value in bytes.

RETURN VALUE
       Upon  successful	 completion,  the tt_message_context_bval function re-
       turns 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_POINTER
		 The pointer passed does not point to an object	of the correct
		 type for this operation.
