16 This function waits for the specified number of milliseconds.

18 Passing 0 as parameter will not wait, but just yield. This can be use‐
19 ful in order to "play nice" with other processes. Other values will
20 cause CPU time to be dropped on most platforms. This will look better
21 to users, and also does things like saving battery power and making
22 fans less noisy.

24 Note that calling this inside your active game loop is a bad idea, as
25 you never know when the OS will give you the CPU back, so you could end
26 up missing the vertical retrace and skipping frames. On the other hand,
27 on multitasking operating systems it is good form to give up the CPU
28 for a while if you will not be using it.
