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);
}
}
Any help would be appreciated
