My understanding is that `__chvalidchk` is just a helper macro used to implement macro versions of ctype.h functions and does not really have any other purpose. IIRC, it is not documented, and so should not be used directly by users. It should not introduce any breakage in user code. - Kirill Makurin _______________________________________________ Mingw-w64-public mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
