Pyrex: wrapping C struct as Python class

[Edward C. Jones]

I have a C struct and functions that use it:

tiny.h:

     typedef struct {
         int ival;
     } Tiny;

     int square(Tiny* t);

tiny.c:

     int squareit(Tiny* t)
     {
         return t.ival * t.ival;
     }

In C code, I would use "malloc", "free" and "squareit" with Tiny. What 
is the best way to wrap this in Pyrex so Python code can do

     t = Tiny(77)
     print t.ival
     print t.squareit()
     del t
