Because you shouldn't deviate from strtoll. The support should be done firs= t in=20 strtoll and then in whatever you're proposing. Yes, I know I'm asking you t= o=20 convince ISO C and the POSIX standard groups. The reason being that most C++ standard library implementations will delega= te=20 to strtoll or similar functions (like we do in Qt). Asking for functionalit= y=20 different from strtoll means asking for more complexity from library=20 developers. Alternatively, make sure that strtoll could be implemented on top of a plai= n C=20 library routine that is the backend for your new function. That would solve= =20 the problem of complexity. --=20 Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 --=20 ---=20 You received this message because you are subscribed to the Google Groups "= ISO C++ Standard - Future Proposals" group.
