numpy/core/src/multiarray/ctors.c:1157–1167

NUMPY_API * Creates a new array with the same shape as the provided one, * with possible memory layout order and data type changes. * * prototype - The array the new one should be like. * order - NPY_CORDER - C-contiguous result. * NPY_FORTRANORDER - Fortran-contiguous result. * NPY_ANYORDER - Fortran if prototype is Fortran, C otherwise. * NPY_KEEPO

 * dtype->subarray is true, dtype will be decrefed.
