[New-bugs-announce] [issue23708] PEP 475: Add _Py_read() and _Py_write() functions

[STINNER Victor]

New submission from STINNER Victor:

To factorize code handling EINTR, I propose add 2 new functions to fileutils.h: _Py_read() and _Py_write().

Attached patch adds these functions and use them in the os and _io modules.

The code of the functions is based on the code from the os and _io modules. The main change is that the functions now truncate code if greater than PY_SSIZE_T_MAX. Other changes are just refactoring.
