(receive-message socket #!key non-blocking as) procedure

Receive the next message from socket. By default, the message data is returned as a string. This can be changed using the as argument. It can either be string, blob or a procedure. The latter will be called with a data pointer and an integer (the number of bytes). The value returned by the procedure will be the return value of receive-message and should make sure to read the message data. If non-blocking is #t, the function call will not block and return #f if no message is available (default: #f).
