tt_message_context_val(library call)	  tt_message_context_val(library call)

NAME
       tt_message_context_val  —  retrieve the character string of a message's
       context

SYNOPSIS
       #include <Tt/tt_c.h>
       char *tt_message_context_val(
       Tt_message m,
       const char *slotname);

DESCRIPTION
       The tt_message_context_val function retrieves the character string of a
       message's context.

       The  m  argument	 is the opaque handle for the message involved in this
       operation.  The slotname argument describes the context	of  this  mes‐
       sage.

       If  there  is no context slot associated with slotname, tt_message_con‐
       text_val returns a NULL pointer.

RETURN VALUE
       Upon successful completion, the tt_message_context_val function returns
       the  contents  for  the	message	 argument.   The  application  can use
       tt_ptr_error(3) to extract one of the following Tt_status  values  from
       the returned pointer:

       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.

       TT_ERR_SLOTNAME
		 The specified slotname is syntactically invalid.

APPLICATION USAGE
       The  application	 should	 use tt_free(3) to free any data stored in the
       address returned by the ToolTalk API.
