Hi Guys,

In my application I need a way to generate an identifier that is guaranteed
to never recur in the lifetime of the server. The method I'm using now is
to concatentate:

a)Integer time, in seconds,

b)Micro time, in microseconds, and

c)PID

into one string, then to spin-lock or micro_sleep() until the micro_time
changes.

My assumption is that this identifier will be unique because no two
processes can have the same PID at the same time.

Is there a better way?

Thanks, Dave.

P.S.--Application: Linux, Apache, PHP, MySQL, web database stuff.
