STINNER Victor added the comment:
New attempt to support C intmax_t type, since Python 3.6 now supports a subset
of C99: intmax_t-4.patch. Changes:
Add support for C intmax_t type:
Add new conversions functions for PyLong:
PyLong_FromIntMax()
PyLong_FromUIntMax()
PyLong_AsIntMax()
PyLong_AsIntMaxAndOverflow()
PyLong_AsUIntMax()
getargs: add 'm' format
New _testcapi constants: INTMAX_MAX, INTMAX_MIN, UINTMAX_MAX,
SIZEOF_INTMAX_T
Add _testcapi.getargs_m() and _testcapi.test_long_intmax_api()
PyLong_FromVoidPtr() uses PyLong_FromUIntMax()
Use intmax_t in various modules
array, struct, ctypes and memoryview are not modified yet to support intmax_t.
