Create a blocked/unblocked socket?

Hello,
How does one create a blocked socket?
How does one create an unblocked socket?
Where is the Win API documentation for this?
Thank you.

Here is the standard generic code for creating a socket.

The generic code:

Code:

---

//gcc e1.c -lws2_32 -o e1.exe
#include <windows.h>
#include <stdio.h>
#include <winsock.h>

#define PORT (u_short) 44444
#define DEST_IP_ADDR "127.0.0.1"

int main()
{
  WSADATA Data;
  SOCKADDR_IN destSockAddr;
  SOCKET destSocket;
  unsigned long destAddr;
  int status;

  status = WSAStartup(MAKEWORD(1, 1), &Data);
  if (status != 0)
    { printf("WSAStartup unsuccessful\n"); }

  destAddr = inet_addr(DEST_IP_ADDR);
  memcpy(&destSockAddr.sin_addr, &destAddr, sizeof(destAddr));
  destSockAddr.sin_port = htons(PORT);
  destSockAddr.sin_family = AF_INET;

  destSocket = socket(AF_INET, SOCK_STREAM, 0);
  if (destSocket == INVALID_SOCKET) {
    printf("socket unsuccessful\n");
    return(1);
  }

  printf("socket created.\n");
}

Thanks for any help.

I found this:

http://msdn.microsoft.com/library/de...tlsocket_2.asp

Code:

---

//-------------------------
// Set the socket I/O mode: In this case FIONBIO
// enables or disables the blocking mode for the
// socket based on the numerical value of iMode.
// If iMode = 0, blocking is enabled;
// If iMode != 0, non-blocking mode is enabled.
int iMode = 0;
ioctlsocket(m_socket, FIONBIO, (u_long FAR*) &iMode);

That's how it's done. Sockets are blocking by default until you change them with ioctlsocket. Another option you have which I find easier to work with than nonblocking sockets is asynchronous sockets. Read the MSDN documentation for WSAAsyncSelect for more information on that.
