fn inkey(timeout: i32) -> bool { this is so wrong. i can pass only seconds, i either wait 0 seconds or 1 second or N seconds, but i cant wait 10 milliseconds for example.

Can you elaborate? You mean the parameter should be in seconds or you don't find any use to be in milliseconds?

i mean that i cannot pass the timeout as milliseconds, if I call inkey(100) like this, it will wait for 100 seconds instead of 100 milliseconds

the parameter should be in milliseconds and its not, i've tried it, just 10 as in inkey(10) and you will see that the function will wait 10 seconds instead of 10 milliseconds
