Hi. Sorry if this a C question...
I'd like to know more about how file locking works.
First of all, is there an ANSI file locking function (or posix)
or a fuction that works under UNIX GCC?
second of all, if you lock a file and another instance tries to write to
it, what happens? how can you see if a file or region is locked?
TIA,
