Delay in C++?

hello guys i havent been on much on MPGH because of school and more.. but i wanted to ask, how i make a delay? like let it wait for 3 secs then continue.... i know its simple but i forgot and im not the one that likes to search =D (I search for different things) i know it was something like Sleep 3; or something i just cant remember

Sleep(ms);

ms is the amount of seconds to sleep.
Sleep Function (Windows)

There are like a million ways to do it.

You would have to do it like: sleep(3000);

Hmmm... I always had a question about this. Does sleep stop the entire execution from running? Such as if I used sleep in a loop of different functions. Let me show you:

Code:

while(true)
{
void function1(){something;};
void function2(){something;};
void function3(){sleep(3000);};
void function4(){something;};
}

Would the other functions still execute while function 3 is sleeping, because I would imagine they would not and it seems this could cause some problems. if you needed other functions to be regularly updated during the sleep() cycle.

Oh I thought it would be like function 1,2,3 would go then it would wait 3000 and then function 4 would

If they're running in the same thread, yes. In simpler terms, if you haven't forked or created a new thread knowingly, then yes it will. I'd explain more but it'd require a whole article on threads, and how Windows does multi-threading.

This is solved by either writing a multi-threaded application, or, instead of performing a sleep, comparing the current time to the last time the function was executed to see if it should execute or just return.

Oh that sounds like a much better idea. I think I made my own sleep function a while back, by accessing the system clock. I never thought to use it to return... o_O

By return I mean (pseudo code)

Code:

if(lastTimeChk+sleepTime > checkCurTime()) return 0; //End execution of method here

rest of the method's code
