I have the hardest time keeping that straight--yes, the latter: const char *service is a pointer to a string that must not be changed; the compiler won't allow assignment to *service (or service[n]). But assignment to service is fine.
But if you use
typedef char *char_p;
then const char_p service declares a variable that you can't assign to! That is, you can initialize it, but never change it. There's some binding here that's hard to figure out... I don't know how you'd declare such a service without the typedef. It's as if the first version is (const char) *service, and the second is const (char *) service--but I believe these parenthesized declarations are not the correct syntax.
Heh, you learn something new every day ;-) now for how to fix the minimum width of the send-msg window...
