My programme listens for just one connection once... the programme just gets stuck at clientSocket = serverSocket.accept() if no client connects. I mean I can't even interrupt it by closing my window. I can't click any of my buttons in the frame etc. I've used this code the same way in my other programmes but it's worked fine (I can cli...
Hello, There is a function assign in Boost.Asio sockets, however I'm looking for something like release/unassign that would transfer the ownership on socket back to user. or some type of assign that would not transfer ownership to socket class, so it would not close it when destroyed. I'm aware of this solution but it involves d...
I wanted to know how to flush the socket streams while doing socket programming in C. I tried all the options- setting TCP_NODELAY using the following code- setsockopt(sockfd, IPPROTO_TCP, TCP_NODELAY, (char *) &flag, sizeof(int)); Note: all the flag and sockfd are declared correctly. I used this function both before send() an...
I need to set the DSCP field of packets sent from a specific (tcp) socket in windows XP. It seems that the GQOS API should serve this purpose (see http://blogs.msdn.com/wndp/archive/2006/07/05/657196.aspx) but I really, really, can't find any working example or figure how to use it on my own. I would be very grateful if anyone of you h...

Hi all; Below is the code fragment I have issue with socket programing. Here after select call, If I do not put a sleep on line 9, on Windows XP, 1 byte is received on line 11 (instead 4 byte is sent from server as integer), when I check xmlSize, it is set to 0. Because iResult is 1, execution continues and on line 15 second receive is c...

Hi all, I'm doing a bit of coursework for university and I'm completely baffled. Basically I've made a basic web server (which uses sockets) in C. I've now got to make it so that any .php file, is run through the php compiler and output. The problem I'm having is that I've tried using system() and execlp() (the latter was recommended b...
