Error using the usleep function as the compiler says " 'usleep' was not declared in this scope despite" including all needed libraries

My code is as follows:

#include <stdlib.h>
#include <time.h>
#include <unistd.h>
#include <windows.h>

int main()
{
    printf("test");
    usleep(1000000);
    printf("test");


    return 0;
}

I am being told "error: 'usleep' was not declared in this scope". I am using the c free compiler if that makes a difference and am completely unsure of why this code is not compiling as all needed libraries are included.

errors: "EINVAL usec is not smaller than 1000000. (On systems where that is considered an error.)" – gstukelj Oct 22 '19 at 19:46
you can use Sleep(1000); – phoenixstudio Oct 22 '19 at 19:46

I cannot use Sleep(1000); as I am on a unix system, additionally I recieve the same error – MrMoglin Oct 22 '19 at 19:49
Thanks for the answer Hogan :) – MrMoglin Oct 22 '19 at 19:49

Why `#include ` if you are on a Unix system? – Weather Vane Oct 22 '19 at 20:13
if you are in linux use #include // UNIX standard function definitions – M.Hefny Feb 09 '21 at 01:43
