修正FireBird 2.X 删除文摘功能的BUG

一、在bbs.c里添加下面这段函数代码
int
cmpdigestfilename(digest_name,fhdr)
char *digest_name;
struct fileheader *fhdr ;
{
    if(!strcmp(fhdr->filename,digest_name))
        return 1 ;
    return 0 ;
}     /* comapare file names for dele_digest function. Luzi 99.3.30 */

二、然后用下面的代码替换掉原来bbs.c里的dele_digest函数
int
dele_digest(dname,direc)          /* updated bye Luzi 99.3.30 */
char *dname;
char *direc;
{
     char digest_name[STRLEN];
     char new_dir[STRLEN];
     char buf[STRLEN];
     char *ptr;
     struct fileheader fh;
     int  pos;

     strncpy(digest_name,dname,STRLEN);    
     strcpy(new_dir,direc);

     digest_name[0]='G';
     ptr = strrchr(new_dir, '/') + 1;
     strcpy(ptr, DIGEST_DIR);
     strncpy(buf,currfile,STRLEN);
     strncpy(currfile,digest_name,STRLEN);
     pos=search_record(new_dir, &fh, sizeof(fh), cmpdigestfilename, digest_name);
     if(pos<=0)
     {
        return;
     }
     delete_file(new_dir,sizeof(struct fileheader),pos,cmpfilename);
     strncpy(currfile,buf,STRLEN);
     *ptr='\0';
     sprintf(buf,"%s%s",new_dir,digest_name);
     unlink(buf);
     return;
}
