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:
That's about the easiest way I can think of (which doesn't eliminate
the possibility of easier or more effective approaches).
The problem is that "write()" just takes one file descriptor, and
that's the choke point for output. You could write an "intercept"
function that takes control when write() is called, uses its args to
write to other fd's (that have been set up earlier) and then passes
control to the real "write()". That's a lot of work, though.
