Sendto-Receivefrom buffer size in blocking mode ?
Posted on 1997-06-18
I'm working with winsock api (wsock32.dll), in UDP blocking mode. First, it seems you cannot receive a buffer more than 30 000 bytes, although you can send correctly the same buffer, "sendto()" returns Ok after sending 30 000 bytes but the distant host who have made an "receivefrom()" is always in the blocking mode. Second, even if the distant host can receive 20 000 bytes buffer size, sometimes to time, the host is blocked again on "receivefrom()".
Can you explain this ? What are the limits of winsock ?
