sleep indefinitely

开发者_Python百科I was wondering if there is a statement which I can use to have a program sleep indefinitely (probably using sleep function??). (I am obviously doing this waiting for a signal that is going to be delivered at some time to this process and it will wake it up)

You want pause().

EDIT: The most likely circumstances under which you might want to use pause() will actually cause a race condition, so prefer sigsuspend().

On Unix, see either pause or sigsuspend.

And on Windows use Sleep(INFINITE)
