Is it possible, to via some low level API, set up a file descriptor so that any data written to it, will be echoed to 2 or more other file descriptors? I want to redirect the output of NSLog, to my own logfile, while keeping all current destinations of log messages. The only way I've found so far is to call the following function: int setup_logging() { int pipes[2]; int result = pipe(pipes); int f = fork(); if (f) { /* parent */ dup2(pipes[1],2); close(pipes[1]); close(pipes[0]); return 0; } else { dup2(pipes[0],0); close(pipes[0]); close(pipes[1]); execlp("/usr/bin/tee","tee","/Users/emac/Desktop/log",0); fprintf(stdout,"failed\n"); exit(1); } } ----------------------------------- See the amazing new SF reel: Invasion of the man eating cucumbers from outer space.
