New submission from Joannah Nanjekye <[email protected]>:
I suggest implementing a C-API for copying data into a buffer exported by an
obj. i.e
int PyObject_CopyToObject(PyObject *obj, void *buf, Py_ssize_t len,
char fortran)
as was intended in PEP 3118. The documentation there says this functionality
should:
"Copy len bytes of data pointed to by the contiguous chunk of memory pointed to
by buf into the buffer exported by obj. Return 0 on success and return -1 and
raise an error on failure. If the object does not have a writable buffer, then
an error is raised. If fortran is 'F', then if the object is multi-dimensional,
then the data will be copied into the array in Fortran-style (first dimension
varies the fastest). If fortran is 'C', then the data will be copied into the
array in C-style (last dimension varies the fastest). If fortran is 'A', then
it does not matter and the copy will be made in whatever way is more efficient."
