       Tt_status tt_message_context_bval(

       unsigned char **value,
       int *len);

DESCRIPTION
       The tt_message_context_bval function retrieves the byte-array value and length 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.  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 returns the status of the operation as one of the following Tt_status val-
       ues:

       TT_OK	 The operation completed successfully.
