These two functions have mutually-recursive definitions in the docs (which is to say, none). |

Something very simple:
PyObject *
PyLong_FromVoidPtr(void *p)
{
#if SIZEOF_VOID_P <= SIZEOF_LONG
return PyInt_FromLong((long)p);
#else
#ifndef HAVE_LONG_LONG
# error "PyLong_FromVoidPtr: sizeof(void*) > sizeof(long),
but no long long"
#endif
#if SIZEOF_LONG_LONG < SIZEOF_VOID_P
# error "PyLong_FromVoidPtr: sizeof(LONG_LONG) < sizeof
(void*)"
#endif
/* optimize null pointers */
if (p == NULL)
return PyInt_FromLong(0);
return PyLong_FromLongLong((LONG_LONG)p);
#endif /* SIZEOF_VOID_P <= SIZEOF_LONG */
}

Logged In: YES user_id=31435 Nope. Guido checked them in 5 years ago, in rev 1.48. To judge from the checkin comment, the code may actually have come from Greg Stein. I don't have time for it, so unassigning. |

Logged In: YES user_id=1188172 I think the definitions are pretty clear to understand. PyLong_FromVoidPtr makes a long from a pointer, PyLong_AsVoidPtr makes a pointer from a long... closing as Works for Me. |
