How can you suppress all logging in Cocoa app?

Question

Is there a way to force suppression of all logging in a Mac OS X desktop Cocoa app?

Sometimes some part of the system or a plugin (which is out of your control) will log messages on behalf of your application to the console (system.log).

Is there a way to suppress all logging in your application?

Answer 1

You could use freopen to change where stdout and sterr point to:

Answer 2

@gabe: was just going to suggest something similar - just tried it out, and a simple 'fclose(stderr)' seems to prevent any output.

Answer 3

I've also done this whenever I've needed to redirect console output to a custom view:

stderr->_write = RedirectOutputToView;
stdout->_write = RedirectOutputToView;

Where RedirectOutputToView has the following prototype:

int RedirectOutputToView(void *inFD, const char *buffer, int size);
