sleep() URGENT!!!!!!!

i need help!!! i wan the dots to appear one by one. but i got errors. 'sleep' is not a member of 'global namespace' and 'sleep' is undeclared identifier.
#include <stdio.h>

main()
{
int counter;

for(counter=0;counter<10;counter++)
{
printf(".\n");
sleep(?????);
}

return 0;
}

Try
#include <winbase.h>
...
Sleep(1000);

Hi,
you didn't mention which operating system and platform you tried this.
In Turbo C++, I think you should use Delay(...); instead of sleep();
In Windows,and VC++, you try with Sleep(..); // Capital 'S'
Include the header file "Winbase.h" also.
thanks

Use delay(); instead of sleep....
SleepEx or Sleep is for the Windows application
