Again, moving slowly towards my readv/writev patch, here's a little patch to simplify the fhandler_socket sendto / recvfrom code. SUSv3 says that recvfrom, recv, and read are all equivalent on sockets if no flags or addresses etc. are provided (and ditto for sendto, send, and write). So, this patch makes that true, partly by removing some methods and making others just delegate to each other as appropriate. In detail: *) I missed a couple of buflen == 0 checks in "net.cc" from my last patch. *) I've removed fhandler_socket recv and send methods and made the cygwin_recv/send functions delegate to the cygwin_recvfrom/sendto functions, with relevant default extra arguments. *) The fhandler_socket read and write methods also delegate now to recvfrom and sendto (rather than to recv and send as previously). *) In all of this I discovered that fhandler_socket::sendto couldn't handle a NULL address: patched too. Enjoy! // Conrad p.s. This saves 1.5K on the DLL size! Happy happy, joy joy!
