Hi All,
Someone on the Forum (or was it here?) mentioned a problem where they couldn't
use the Airport Search dialog easily because some airports in apt.dat are named
in mixed case while some are in all-caps.
Rather than attempt to fix apt.dat (I'm not completely mad ;) ), I've created a
small patch to our airport search function so that this search is done
case-insensitively. I've done some minimal testing, and it at least appears to
be functionally correct.
However:
a) As I'm sure many people are already aware, I'm not a very good C programmer,
so there may be a better way to do this that I'm missing
b) This uses the strcasestr() function, which is part of the GNU C library in
string.h. What is the best way to check that such a function is available on
all our platforms?
