Equivalent to window.setTimeout() for C++
- by bobobobo
In javascript there's this sweet, sweet function window.setTimeout( func, 1000 ) ; which will asynchronously invoke func after 1000 ms.
I want to do something similar in C++ (without multithreading), so I put together a sample loop like:
#include <stdio.h>
struct Callback
{
// The _time_ this function will be executed.
double execTime ;
// The function to execute after execTime has passed
void* func ;
} ;
// Sample function to execute
void go()
{
puts( "GO" ) ;
}
// Global program-wide sense of time
double time ;
int main()
{
// start the timer
time = 0 ;
// Make a sample callback
Callback c1 ;
c1.execTime = 10000 ;
c1.func = go ;
while( 1 )
{
// its time to execute it
if( time c1.execTime )
{
c1.func ; // !! doesn't work!
}
time++;
}
}
How can I make something like this work?
