好像还是有问题

struct UCACHE {
    ucache_hashtable hashtable;
    ucache_hashtable hashusage;
    int hashhead[UCACHE_HASHSIZE + 1];
    int next[MAXUSERS];
    time_t uptime;
    int number;
#ifdef HAVE_CUSTOM_USER_TITLE
    char user_title[255][USER_TITLE_LEN]; //定义用户的称号字符串。
#endif
    struct userec passwd[MAXUSERS];
    int idnumber; //自己加的
};


然后
static void countidnumber(void)
{
    int i,idnum=0;
    for (i=0;i<MAXUSERS;i++)
        if (uidshm->passwd[i].userid[0])
            idnum++;
    uidshm->idnumber = idnum;
}    

int getidnumber(void)
{
    int i,fd;
    fd = ucache_lock();
    i = uidshm->idnumber;
    ucache_unlock(fd);
    return i;
}    


在flush_ucache的return前加上countidnumber();
在load_ucache的ucache_unlock(fd)前加上countidnumber();

然后BBS又上不了了。本地telnet 127.0.0.1显示

Trying 127.0.0.1...
