What's the problem?

From /root/src/boinc/db/db_base.C

int DB_BASE::enumerate(char* clause) {
int x;
char query[MAX_QUERY_LEN];
MYSQL_ROW row;

if (!cursor.active) {
cursor.active = true;
sprintf(query, "select * from %s %s", table_name, clause);
x = mysql_query(db->mysql, query);
if (x) return mysql_errno(db->mysql);
cursor.rp = mysql_store_result(db->mysql);
if (!cursor.rp) return mysql_errno(db->mysql);
}
row = mysql_fetch_row(cursor.rp);
if (!row) {
mysql_free_result(cursor.rp);
cursor.active = false;
return 1;
} else {
db_parse(row);
}
return 0;
}

Ok, so when a row is NOT found it returns a 1, but if a row is found it returns a 0. Now, take a look at /root/src/boinc/sched/main.C

found = false;
while (!gproject.enumerate("")) {
found = true;
}
if (!found) {
log_messages.printf(SchedMessages::CRITICAL, "can't find project\n");
exit(1);
}

Is that right? While we find rows, gproject.enumerate("") returns 0. Yeah, it looks right... are we getting an error?
