MetaDB question

[Russ]

Has anyone managed to get metadb_getMetaData to return anything sensible with numeric types such as MT_LENGTH, or is it just me? All I seem to be able to get is rubbish. Maybe it's just because I'm not a C++ programmer at heart but it seems a bit stupid returning a number using a char* type .

I'm 99% finished on a new Winamp3/mIRC plugin which works using the new mIRC SendMessage interface, and is hopefully more configurable than my previous one . I'd like to get track length and so implemented though.

It returns the number of milliseconds. So 10000 is ten seconds long. Also, it uses a char* interface along with a type parameter so one function can access any kind of metadata.

since you know it's an int, you'd do something like this to make the return value what you need it to be:

int * len = (int *)metadb_getMetaData(...);

No... no, you wouldn't. That's plain wrong. Ignore what he just said.

You would do:
int val=0;
api->metadb_getMetaData(playstring, MT_LENGTH, (char *)&val, sizeof(val), MDT_INT);

haha, that's horrible, i should look at the function prototype before answering next time.

That's cause Aus has overloaded the casting functions so it is ULTRA smart. Maybe you should check with him first Brennan.

[Aus]

yes, and my iq has magically risen 20 points =)

Ah that makes it a bit clearer... types in C++ confuuse me .
