I believe we will have to use connect, since ConnectEx is only supported on connection-oriented sockets. (Ref: http://msdn.microsoft.com/en-us/library/windows/desktop/ms737606(v=vs.85).aspx) I've uploaded a simple (albeit poorly written) program that connects to a socket and sends out an ICMP Ping packet to a server using connect() that you could use as a reference. (see ping.c). For some reason the receive component does not work in the program. The program will require linking in the WS2_32.lib library for the Winsock API. Attachments:

jleimon, Did you try applying mikio's change https://golang.org/cl/12843043/ to see if it fixes your problem? You don't need to change test files, just the fd_windows.go. Thank you. Alex |
