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

Question

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.

You need just to include:

#include <unistd.h>
