Question

Problem:

• Call to send(), returns Winsock Error 10038 against socket handle

Illustration:

acceptedSocket = accept (server, (sockaddr *)&sin, &len); 

• accept(), returns 0
  • A new thread, is created for each connection
  • send(), (in thread function) returns 10038

Illustration: – in thread function

//omitted SOCKET RemoteSocket = (SOCKET) client; //omitted send (RemoteSocket, stringToSpend, strlen(stringToSpend), 0) 

Suggestions:

• Possible, race condition?
• Could use I/O completion ports, but not at this stage

Answer 1

Isn’t the problem in the line

acceptedSocket = accept (server, (sockaddr *)&sin, &len) == INVALID_SOCKET) 

You make acceptedSocket the result of the comparison, but you should store the actual socket returned from accept somehow:

acceptedSocket = accept (server, (sockaddr *)&sin, &len); isOK= acceptedSocket!=INVALID_SOCKET; 

Although I’m a bit confused by the unbalanced parentheses in your post, so I may be wrong
