Ok, the question is how many functions in POSIX.pm need to be migrated? Quite a number are implemented as Perl. Only a few do anything non-trivial, so migrating them all to C is certainly feasible. As for which ones need to be in C for locale purposes, aside from tolower and toupper, the only candidates I see (that is actually implemented) is strerror. But I may have missed some, and maybe there are some others that have subtle bugs due to being implemented in Perl? AndrewThread Previous | Thread Next
