1 2/* Capsule objects let you wrap a C "void *" pointer in a Python3   object.  They're a way of passing data through the Python interpreter4   without creating your own custom type.5 6   Capsules are used for communication between extension modules.7   They provide a way for an extension module to export a C interface8   to other extension modules, so that extension modules can use the9   Python import mechanism to link to one another.10 11   For more information, please see "c-api/capsule.html" in the12   documentation.13*/14 15#ifndef Py_CAPSULE_H16#define Py_CAPSULE_H17#ifdef __cplusplus18extern "C" {19#endif20 21PyAPI_DATA(PyTypeObject) PyCapsule_Type;22 23typedef void (*PyCapsule_Destructor)(PyObject *);24 25#define PyCapsule_CheckExact(op) Py_IS_TYPE((op), &PyCapsule_Type)26 27 28PyAPI_FUNC(PyObject *) PyCapsule_New(29    void *pointer,30    const char *name,31    PyCapsule_Destructor destructor);32 33PyAPI_FUNC(void *) PyCapsule_GetPointer(PyObject *capsule, const char *name);34 35PyAPI_FUNC(PyCapsule_Destructor) PyCapsule_GetDestructor(PyObject *capsule);36 37PyAPI_FUNC(const char *) PyCapsule_GetName(PyObject *capsule);38 39PyAPI_FUNC(void *) PyCapsule_GetContext(PyObject *capsule);40 41PyAPI_FUNC(int) PyCapsule_IsValid(PyObject *capsule, const char *name);42 43PyAPI_FUNC(int) PyCapsule_SetPointer(PyObject *capsule, void *pointer);44 45PyAPI_FUNC(int) PyCapsule_SetDestructor(PyObject *capsule, PyCapsule_Destructor destructor);46 47PyAPI_FUNC(int) PyCapsule_SetName(PyObject *capsule, const char *name);48 49PyAPI_FUNC(int) PyCapsule_SetContext(PyObject *capsule, void *context);50 51PyAPI_FUNC(void *) PyCapsule_Import(52    const char *name,           /* UTF-8 encoded string */53    int no_block);54 55#ifdef __cplusplus56}57#endif58#endif /* !Py_CAPSULE_H */59
