signal.alarm function with resolution greater than 1 second?

I'm trying to build a python timeout exception that runs in milliseconds.

The python signal.alarm function has a 1 second resolution.

How would one get an equivalent function that requests a SIGALRM signal to a given process in, say milliseconds, as opposed to seconds?

I've found no simple solutions as of yet.

Thanks in advance 开发者_JAVA百科for your input.

Use signal.setitimer() instead.
