Hi...
I probably shouldn't send this here, but the only other place
I can think of is comp.lang.c, and I don't get that newsgroup :( And
last time I checked out that group on another system...it was a bunch
of DOS users :(
I've written some code, that, for the life of me, I can't figure
out why its giving me the results it is:
The fragment of code looks like:
-----------------
dblist *head, *temp;
head = temp = get_dbrec("userid", "template", "advanced", "geoff");
fprintf(stderr, "userid=%s\n", head->value);
while(temp != NULL) {
temp->value = get_valuer(content, temp->name);
fprintf(tfile, "%-20s [%s]: %s [%s]\n", temp->name,
head->name,
temp->value,
head->value);
temp = temp->next;
}
fprintf(stderr, "userid=%s\n", head->value);
-----------------
the structure dblist looks like:
typedef struct data {
char *name;
char *value;
struct data *next;
struct data *key;
} dblist;
Now, get_dbrec() pulls a record out of a postgres95 database
file, and initialize a linked list of values...and it does this correctly.
After initializing, head->value == "template", which is correct,
and what I'm expecting.
When I run the code, the output looks like:
userid [userid]: scrappy@ki.net [scrappy@ki.net]
fname [userid]: Marc [Marc]
street [userid]: []
city [userid]: []
state [userid]: []
phone [userid]: []
job [userid]: No Answer [No Answer]
terms [userid]: Qualify [Qualify]
score [userid]: 0 [0]
pcode [userid]: []
faxphone [userid]: []
Which is where the problem is. head->name, which points at the
beginning of the list, has the correct value in it all the way through
the while() loop, but for some reason, head->value keeps taking on the
new value, even though I'm not assigning it a new value anywhere, or
at least, not that I can figure out. The value of 'head->value' *should*
remain as 'scrappy@ki.net', just like 'head->name' is 'userid'.
I realize that I'm probably missing something *really* stupid, but
after working on this for 3 days and trying to figure out the problem, I'm
at a complete loss :(
I also realize that there is probably incomplete data here as well,
but can't think of anything else to add :(
Any ideas of where I should look, or what I'm missing?
thanks...
