What are the contents of 'word'? How big is the 'sql' buffer?

the contents of word were OL, and the sql buffer is 1000, so there is no issue there. when i remove the %%, the output is normal, it only messes up when i put in the two percentage signs.

Is it possible that the MUD is interpreting those symbols somehow?

See the following:


[david@thebalrog:~]$ cat test.c

#include <stdlib.h>
#include <stdio.h>

int main(char ** argv, int argc)
{
    char buf[1000];
    const char * word = "OL";

    sprintf(buf,"select * from dictionary where word like '%s%%'\n", word );
    printf(buf);

    return 0;
}

[david@thebalrog:~]$ gcc test.c -o test
[david@thebalrog:~]$ ./test                            
select * from dictionary where word like 'OL%'
[david@thebalrog:~]$

I use the \n because otherwise zsh gets a little confused.

Anyhow, it comes out correctly...

I would try, on the MUD, using printf instead of bug and see if it does the right thing. (Of course you will have to look at the logs.)

yeah i guess for whatever reason it wasn't showing up correctly either because of valgrind or the mud, but wrote up a little function to check words and it worked just fine.

Ok well after exhausting debugging and changes, I finally have a working version of this scrabble game. All the variables are now in the character structure. Instead of using an array of current words i decided to hold an array of integers pointing to the letter on the board instead. I have a couple problems however that I could use an outside opinion on.

1.) Not going in correct order, in terms of direction it might go fine up through the 4th letter but the 5th letter is 3 spaces away instead of adjacent to the last square.

2.) Non-words not being cut off when determined not a word. IE words like IUIRPU being checked in the dictionary when it shouldn't have made it past IU. I was even checking the code on my friends server, which does not even have access to my database, so techincally no words should have gone past two letters, but they were anyways.

Thats the two files scrabble.c and scrabble.h pasted into one file, as well as the mud.h definitions and declarations. Any helps would be appreciated thanks.

****EDIT*****
After more debugging and changing I have fixed those two errors, and the code is actually working now. I still have some memory leaks to track down so back to valgrind.
