Is the conio.h header file supported by gcc?

Question

#include <stdio.h>
#include <conio.h>

int main() {
    printf("hello world");
    getch();
    return 0;
}

I'm using gcc 13.1, and I've read in an article that gcc doesn't support the conio.h file, but the above code is working fine without any errors or warnings.

Does GCC support <conio.h>?
