The question is: Why do you create this file beforehand? If a file
needs to be
created apr_global_mutex_create will do this for you.
Good question. Let me present the problem at a high level. There's a
file that is regularly refreshed, and I only want one request handler
rebuilding it at a time, because otherwise there are lots of horrible
race conditions. I don't know whether I'm in worker or prefork
mode. So I simply want to serialize update of this file, and I
thought apr_global_mutex_* was a good way to do this. Is there a
better way? -Tim
