need help with sockets
anyone and teach me how to save standard output to a file in a client/server socket. I know how to read them to the screen but i'm not quite sure how to save them to a file.
my read to screen file code:
memset(line, 0x0, LINE_ARRAY_SIZE);
while (recv(connectSocket, line, MAX_MSG, 0) > 0) {
cout << " -- " << line << "\n";
if (send(connectSocket, line, strlen(line) + 1, 0) < 0)
cerr << "Error: cannot send modified data";
memset(line, 0x0, LINE_ARRAY_SIZE); // set line to all zeroes
i wanna save the display to a file for example abc.txt.
really hope sum1 can help me, thanks.
