Do "Sleep()" exists in C Language?

Hi,
Perhaps I am asking a silly question, but I really don't know about it. Can anyone tell me the function for "sleep" kind of functionality in C language for Unix. I don't think any function with the name of sleep() exits in Unix's C language. or perhaps I am not known with the header file required for this. Can anyone guide me about the correct function to halt the program execution for a specified time? Do tell me the header file required for the function as well.

Regards,

I don't think there is (correct me if I'm wrong). The usual hack is:

Code:

---


#include <time.h>

void wait(unsigned timeout)
{
 timeout += clock();
 while(clock() < timeout)
  continue;
}

There is no sleep function in standard C, but your OS may provide such a function. What OS are you using? In case of a Unix-like OS there is function sleep(), it's part of the POSIX standard, you need to include unistd.h for that.
