Function PyArray_Converter

numpy/core/src/multiarray/conversion_utils.c:41–56

NUMPY_API * * Useful to pass as converter function for O& processing in PyArgs_ParseTuple. * * This conversion function can be used with the "O&" argument for * PyArg_ParseTuple. It will immediately return an object of array type * or will convert to a NPY_ARRAY_CARRAY any other object. * * If you use PyArray_Converter, you must DECREF the array when finished * as you get a new reference

 * as you get a new reference to it.
