имеется irc сервер, вот часть кода проверяющая корректен ли никнейм

s_user.c
------------------------------------------------------
/*
* 'do_nick_name' ensures that the given parameter (nick) is really a proper
* string for a nickname (note, the 'nick' may be modified in the process...)
*
* RETURNS the length of the final NICKNAME (0, if nickname is invalid)
*
* Nickname characters are in range 'A'..'}', '_', '-', '0'..'9'
* anything outside the above set will terminate nickname.
* In addition, the first character cannot be '-' or a Digit.
*
* Note:
* The '~'-character should be allowed, but a change should be global,
* some confusion would result if only few servers allowed it...
*/

static int do_nick_name(char *nick)
{
Reg1 char *ch;

if (*nick == '-' || isDigit(*nick)) /* first character in [0..9-] */
return 0;

for (ch = nick; *ch && (ch - nick) < NICKLEN; ch++)
if (!isIrcNk(*ch))

}
------------------------------------------------------
isIrcNk на сколько я понимаю таблица допустимых символов

про него упомянается только в common.h

#define NTL_IRCNK 0x1000 /* Nick names charset, aka isvalid() */
.
.
.
#define isIrcNk(c) (NTL_char_attrib[(c)-CHAR_MIN] & NTL_IRCNK)

про NTL_char_attrib упомянается в common.c
-------------------------------------------------------

ВОПРОС:
