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  charac-
     ter 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 con-
     text of this message.

     If there  is  no  context  slot  associated  with  slotname,
     tt_message_context_val() returns a NULL pointer in slotname.

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 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_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.

SEE ALSO
     tt_c(5), tt_ptr_error(3), tt_free(3).
