fopen question

Hi,

I'm attemptimg to add data to a text file but am worried what happens if
two (or more) click the 'submit' button at the same time. Does fopen()
return a NULL if the file is busy? What would be the best way to do this -
should I put a in sleep(1) and try again in a loop?

Any help appreciated, thanks.

Paul

You're really looking for a way to synchronize file access. Check out
