这篇手册描述了给那些想使用pycairo来写扩展模块的C和C++程序员使用的API。

访问Pycairo 的 C API

下面的例子展示了如何导入 pycairo的API:

#include "py3cairo.h"

PyMODINIT_FUNC
PyInit_client(void)
{
  PyObject *m;

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