strrchr

Hi everyone,

Does anyone know why the old C function "strrchr" has been implemented in C++ as

Code:

---

const char * strrchr ( const char * str, int character );
      char * strrchr (      char * str, int character );

---

and not as

Code:

---

char * strrchr ( const char *, int );

---

Some old C libraries won't compile anylonger...

Thanks!

strrchr returns a pointer to the character found (or a null pointer otherwise). As such, it makes sense that if you pass it a pointer to something that should not be changed, you get back a pointer to something that should not be changed.
