What is meant by the 'usleep'

[quisite]

int main()
{
int i=0;
int count =0;
cout<<"Please Input Speed Of Timer (ms):";
cin>>second;
for(;;)
{
for(i=0;i<second;i++)
{usleep(100*100);}
printf("%d\n",count++);
}
return main();
}

What is mean by 'usleep(100*100)' &
'printf("%d\n",count++)' .

int main()
{
	int i=0;
	int count =0;
	cout<<"Please Input Speed Of Timer (ms):";
	cin>>second;
	for(;;)
	{
	for(i=0;i<second;i++)
	{
		usleep(100*100);
	}
	printf("%d\n",count++);
	}
	return main();
}

Next time, use code tags.

Convenient help is to google "man funcname". Try "man usleep", for example.

(For those programming on Windows, use "msdn" instead of "man".)
