Hello, The following program hangs when its pipes are closed in the same order in which they were opened, and terminates when its pipes are closed in the reverse order. I've never seen this on other platforms - it a bug? Or is there a subtlety I'm unaware of? Thanks --John ---------------------------------------- #include <stdio.h> int main (void) { FILE *pipe1; FILE *pipe2; pipe1 = popen ("cat", "w"); pipe2 = popen ("cat", "w"); /* hangs unless pipes are pclosed in order pipe2,pipe1 */ pclose (pipe1); pclose (pipe2); return 0; } -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
