- 主题:封禁匿名版面内匿名用户掉线的gdb调试信息
第一次成功的执行了gdb...各位帮忙看看错误该如何修改吧
BBS正常登陆，进入匿名版面内，将光标定位到匿名发文的文章前
切换到linux(debian)终端界面，用ps aux|grep bbsd找到当前登录进程的pid
进入gdb
(gdb) attach pid
(gdb) c
Continuing.
回到BBS，在匿名版面内，匿名发文的文章前按Ctrl+Y
再回到gdb调试界面，出现提示
Program received signal SIGSEGV, Segmentation fault.

bt出来的信息看得不是太明白，我看大致意思是
执行到deny_anony函数里的giveup_addpost函数中的getuser函数出错，相关部分代码
/* stiger,增加封禁某人的发文权限1天 */
int giveup_addpost(char *userid){
struct userec *user;
int i,s[GIVEUPINFO_PERM_COUNT];
if(!(getuser(userid,user)))
return 0;
get_giveupinfo(user,s);
s[1]=-(1+(!s[1]?(time(NULL)/86400):((s[1]<0)?(-s[1]):s[1])));
user->userlevel&=~PERM_POST;
return (save_giveupinfo(user,s)+1);
}
以及
int getuser(const char *userid, struct userec **user)
{ /* 取用户信息 */
int uid = searchuser(userid);
if (uid == 0) {
if (user)
*user = NULL;
return 0;
}
if (user)
*user = &uidshm->passwd[uid - 1];
return uid;
}
没看出来问题所在....请各位指点~

hoho~
原来如此:)
唉，由此可见我C语言水平还是太凹...努力！
