Subject: Does RSTRING_PTR() return a '\0' terminated C?

Hi, in a Ruby C extension I need to get a '\0' terminated string given
a Ruby string. I'm just interesed in Ruby 1.9.

I'm testing that RSTRING_PTR(str) does returns a '\0' terminated
string, ot it seems so, but I'm not sure. Source code says:

#define RSTRING_PTR(str) \
    (!(RBASIC(str)->flags & RSTRING_NOEMBED) ? \
     RSTRING(str)->as.ary : \
     RSTRING(str)->as.heap.ptr)

Honestly, no idea about what it does :)

So, can somebody ensure me that RSTRING_PTR() returns a pointer to C
char finished with '\0'?

Thanks a lot.
