7.5.2 CObjects
- PyCObject
-
This subtype of 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.
- PyObject * PyCObject_FromVoidPtr(void* cobj,
void (*destr)(void *))
-
Creates a PyCObject from the void * cobj. The
destr function will be called when the object is reclaimed.
- PyObject * PyCObject_FromVoidPtrAndDesc(void* cobj,
void* desc, void (*destr)(void *, void *) )
-
Creates a PyCObject from the void *cobj. The
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)
-
Returns the object void * that the PyCObject self
was created with.
- void * PyCObject_GetDesc(PyObject* self)
-
Returns the description void * that the PyCObject
self was created with.
