Note that strscpy() supports the 3 argument version of glibc, and POSIX has always been willing to standardize a subset of a particullar interface. Otherwise, any Legacy Unix system which added some one or more flags to some particular interface could potentially disqualify anything with the same name of that interface from ever being standardized, which is (a) stupid, and (b) not what has been done in historical practice. - Ted
