103 * POSIX.1-2001 specifies _tolower() and _toupper() to be macros equivalent to
104 * tolower() and toupper() respectively, minus extra checking to ensure that
105 * the argument is a lower or uppercase letter respectively. We've chosen to
106 * implement these macros with the same error checking as tolower() and
107 * toupper() since this doesn't violate the specification itself, only its
108 * intent. We purposely leave _tolower() and _toupper() undocumented to
109 * discourage their use.
111 * XXX isascii() and toascii() should similarly be undocumented.
