.. currentmodule:: cairo
This manual documents the API used by C and C++ programmers who want to write
extension modules that use pycairo.

===========================
Example showing how to import the pycairo API::
#include "py3cairo.h"
PyMODINIT_FUNC

{
PyObject *m;
m = PyModule_Create(&clientmodule);
if (m == NULL)
return NULL;
if (import_cairo() < 0)
return NULL;
/* additional initialization can happen here */
return m;
}
