Hi, I have a requirement to have message type based receiving functionality, like the one provided by linux ipc "ssize_t msgrcv(int msqid, struct msgbuf *msgp, size_t msgsz, long msgtyp, int msgflg); " But the messagequeue implementation in boost only allows to set a priority of the message and does not provide a mechanism to wait on a messagequeue based on message type. Can someone tell me if there is a way out to get the above functionalities through boost as well.
