Say i have a function Foo that returns a void * which in my case will actually return a string, if i want the first character of that string is it correct to do ((char *)Foo())[0] ?

Looks good to me but you can just try it:

;compile

#include <stdio.h>

void *foo() {
    return (void *) "abc";
}

int main(void) {
    char *s = "abc";
    printf("%c%c", ((char *) foo())[0],
    ((char *) foo())[1]);
}
