No. Messages to a ptype are blocked during start-up until the ptype
either replies to the message, or issues a tt_message_accept
call. However, the implementation of the ptype can include tt_message_reject for any request it gets that do not have a status of TT_WRN_START_MESSAGE
. All requests will then
be delivered to (and rejected by) all running instances of the ptype before
a new one gets started. This method will be slow if many of these ptypes are
running at the same time, or if the message contains a large amount of data.
Alternatively, you could use tt_message_accept, which basically
unblocks messages to the ptype.
