PyCObject
¶ This subtype of
PyObject
represents an opaque value, useful for C extension modules who need to pass an opaque value (as avoid*
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 *))¶ - Return value: New reference.
Create a
PyCObject
from thevoid *
cobj. The destr function will be called when the object is reclaimed, unless it is NULL.
-
PyObject*
PyCObject_FromVoidPtrAndDesc
(void* cobj, void* desc, void (*destr)(void *, void *))¶ - Return value: New reference.
Create a
PyCObject
from thevoid *
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)¶ Return the object
void *
that thePyCObject
self was created with.
