Pyrex can perform automatic conversion from certain Python types to certain 
C types, so you can specify arguments as 'int' and pass integers, or 'char 
*' and pass strings. The actual values passed to the function when you call 
it from Python are Python objects, and the conversion code is included in 
the compiled function.

There aren't any automatic conversions from a Python object to 'void*'.

Perhaps you meant to use cdef here instead of def. A cdef function is not 
callable from Python, but it can take arguments of any C type.
