What does C "Sleep" function (capital "S") do on a Mac?

Question

Note the capital "S" in Sleep. Sleep with a capital "S" is a standard function that sleeps milliseconds on the PC. On Mac OS X, there is no such symbol. However, the Xcode linking environment seems to find something to link it to. What is it?

Answer 1

Well, it’s an old old Carbon function (in the CoreServices / OSServices framework) that puts the computer to sleep. I can’t find any documentation.
