RE: Blocking sockets problem

["Lim Hock-Chai" <Lim.Hock-Chai@xxxxxxxx>]

Doing some reading and below might be the cause of the problem.

In blocking mode, it seems like recv() will wait for data you specified in the 
length field before return control back.  If during the wait time, the server 
closes the socket, the recv() will receive a return value of 0.

Example: 
1) if you specified the length as 2: recv(hostSock :%addr(recvData) :2 :0) and 
it is in blocking mode
2) If the server sent a one byte data and close the connection, you program 
will get a return value of 0.

Might want to change your program to use the length of 1 to see if this will 
resolve the problem.
