CObjects ¶

警告

The CObject API is deprecated as of Python 2.7. Please switch to the new 胶囊 API。

PyCObject ¶

此子类型的 PyObject represents an opaque value, useful for C extension modules who need to pass an opaque value (as a void* pointer) through Python code to other C code. It is often used to make a C function pointer defined in one module available to other modules, so the regular import mechanism can be used to access C APIs defined in dynamically loaded modules.

int PyCObject_Check ( PyObject *p ) ¶

返回 True 若其自变量是 PyCObject .

PyObject * PyCObject_FromVoidPtr ( void* cobj , void ( *destr )(void *) ) ¶

返回值：新引用。

PyObject * PyCObject_FromVoidPtrAndDesc ( void* cobj , void* desc , void ( *destr )(void *, void *) ) ¶

返回值：新引用。

创建 PyCObject 从 void * cobj 。 destr function will be called when the object is reclaimed. The desc argument can be used to pass extra callback data for the destructor function.

void* PyCObject_AsVoidPtr ( PyObject * self ) ¶

返回对象 void * that the PyCObject self was created with.

void* PyCObject_GetDesc ( PyObject * self ) ¶

Return the description void * that the PyCObject self was created with.

int PyCObject_SetVoidPtr ( PyObject * self , void* cobj ) ¶
