     context

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

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