Multiple function prototype declarations
by Stephen R. van den Berg 23 Sep '16

23 Sep '16

I seem to recall that in C, one can define multiple function declarations for the same function. Is it possible to do the same at Pike level? Example, I have a function declared as void foo(mixed ... bar); Now I want to check, and enforce two different declarations: void foo(string s, mixed ... bar); void foo(function f, string s, mixed ... bar); Can I, at Pike level, declare somehow that the above two prototypes are the only two valid prototypes for this function? So that Pike will give me a syntax error if I try to do foo(23); ? -- Stephen.

Winsock error 10038 when backending sockets and stdin
by Chris Angelico 12 Sep '16

On Unix, you can happily select() on any file descriptors, including stdin and sockets. On Windows, that doesn't appear to be the case. Here's a simple form of netcat: object sock; void sockread(mixed id, string data) { //Restrict to ASCII printables for simplicity write(filter(data, lambda(int c) {return has_value("\t\r\n", c) || (c >= 32 && c < 128);})); } void console(mixed id, string data) {sock->write(data);} int main() { sock = Stdio.File(); sock->connect("minstrelhall.com", 221); sock->set_read_callback(sockread); Stdio.stdin->set_read_callback(console); return -1; } The important aspects of this are read callbacks on both a socket and Stdio.stdin, and returning -1 from main. Comment out the stdin callback and all is well. Keep it in, and the program runs fine on Unix, but on Windows, bombs out: /home/zino/hack/pike8-rel/pike/src/backend.cmod:5496: Fatal error: Filedescriptor 0 (IS CONSOLE) caused fatal error 10038 in backend. Backtrace at time of fatal: -:1: Pike.Backend(0)->`()(3600.0) This happens with both 7.8 and 8.0 stables on Windows 7, though I doubt it'll be any different on other Pikes or Windowses. Is there any good way to respond to console and sockets? For now, I think I'll just write this off as "Windows sucks" and disable the console (it's only a debug/emergency feature anyway). ChrisA
