was looking at the gimps python API, svn - gimp-pdb.c:311
GimpParam *
pygimp_param_from_tuple(PyObject *args, const GimpParamDef *ptype, int
nparams)
{
PyObject *tuple, *item, *r, *g, *b, *x, *y, *w, *h;
GimpParam *ret;
int i, j, len;
gint32 *i32a; gint16 *i16a; guint8 *i8a; gdouble *fa; gchar **sa;
if (nparams == 0)
tuple = PyTuple_New(0);
else if (!PyTuple_Check(args) && nparams == 1)
tuple = Py_BuildValue("(O)", args);
else {
Py_INCREF(args);
tuple = args;
}
if (!PyTuple_Check(tuple)) {
PyErr_SetString(PyExc_TypeError, "wrong type of parameter");
return NULL;
}
if (PyTuple_Size(tuple) != nparams) {
PyErr_SetString(PyExc_TypeError, "wrong number of parameters");
return NULL;
}
--- snip
Notice that tuple is always created, but error values dont free, I think
both "return NULL;"'s need a Py_DECREF(tuple); before them.
