okay...i admit it..i have found a problem that i cannot solve. i have
been working on it for 3 days solid. i need some help in a very bad
way. i'm totally stumped. i've been through all my books, the unix
manual...you name it, i have probably tried it.
my index files are set to read and write all in all my world dirs...i
have even rm'd them and remade them..no luck...
here's what i got. i downloaded obuild(i even mailed sammy..he hasnt
gotten back yet(2 days ago) but thats cool..he's probably really busy..)
i am getting a crash from the zedit create. it adds lines to the index
files after it creates the zones in memory...it does this by creating a
temp file, checking the old index file line by line and
copying/inserting each line appropriately in the new file, then it
copies the new file over the old file..i will post some code and show
the EXACT spot the mud is crashing. and put in some debugging statements
output. if ANYBODY can help me, i will love you for life. debugging
statements in the code will begin with **
The code is interspersed through 3 functions(1 large one, 1 medium one
and one small one, i'll only post the relevant part of the large
one..do_zedit..)
i'm really really really sorry to post such a large letter to the
list..but i'm at my wits end.
here is my debugging output...

here is the problem function...which works with the calls from the zon
section of the code, but not with the wld section..i'm totally friggin
stumped...
int get_line2(FILE * fl, char buf[])
{
int lines = 0;
log("entering get_line2");
if(!fl) return(0);
log("getting line");
if(fgets(buf, 10, fl)) <<<-----right here is where the damn thing
dies.
lines++;
buf[strlen(buf)-1] = '\0';
return(lines);
}
and finally the call to add_to_index for the wld part of the code...
if(!add_to_index(zone, "wld"))
{
send_to_char("Error editing world index\r\n", ch);
return;
}
send_to_char("Added zone to world index\r\n", ch);
the only thing i can figure is that the file doesnt get open for
reading..or the name gets switched along the way...which i'll be darned
if i can find.
