Well, the *obvious* answer is to use strlen() from the standard C-
library. However, if the string can contain null-bytes that doesn't 
work, and then you *must* do someting like:

   PyArg_ParseTuple(args, "s#", &s, &len) // s is (char*), len is int

For more information, and a plethora of other formatting options, read 
the format string specification in the Python documentation: chapter 
"Extending and Embedding", section 1.7: "Extracting Parameters in 
Extension Functions". (I know, you'd expect to find detailed 
information like that in the "Python/C API" chapter, but it isn't.)
