I've been programming C++ and Allegro. I have a String called, "TheText" in
one of my classes which I want to print to the screen with "textout()."
However, the textout() function only does (unsigned char *)'s.
I am lost when it comes to how to convert the String to this, and without
doing that I can't print the text. If someone could help it'd be great.
I've tried a simple typecast: (char *)TheText, and that didn't compile.
I then looked at the _string.h header and found a function, "chars()". This
returns a (const char *).
So I tried: (char *)TheText->chars(); This compiled, but printed garbage
on the screen.
So I tried a: const_cast<char *>(TheText->chars()) which immediately
crashed the program.
The book I've been using says that a String class has a function called
c_str() which returns a (char *). I tried that but the String class
apparently didn't have the function.
Thanks!
