Refer to Extending and Embedding the Python Interpreter,
section 1.12, ``Providing a C API for an Extension Module,'' for more
information on using these objects.
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.
int PyCObject_Check(
PyObject *p)
Return true if its argument is a PyCObject.
PyObject* PyCObject_FromVoidPtr(
void* cobj,
void (*destr)(void *))
Return value:New reference.
Create a PyCObject from the void *cobj. The
destr function will be called when the object is reclaimed,
unless it is NULL.
Create 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)
Return the object void * that the PyCObjectself was created with.
void* PyCObject_GetDesc(
PyObject* self)
Return the description void * that the PyCObjectself was created with.
int PyCObject_SetVoidPtr(
PyObject* self, void* cobj)
Set the void pointer inside self to cobj.
The PyCObject must not have an associated destructor.
Return true on success, false on failure.
