multimedia timers in vc++ 32 bit
Posted on 1998-07-23
I'm writing an app to compose semi random midi music and am having problems getting my head around the documentation regarding multimedia timers in c++. No probs with generating the notes and storing in a list but I need to set up a timer for the "time to next note" with a callback function to take a pointer to the list and play that note with a midiOutShortMsg command. If anyone has any code which would demonstrate this or indeed anything which demonstrates how the callback is called and a pointer passed to it I would be eternally grateful.
From the documentation I've seen it's not clear whether the callback function has to be in a fixed code segment in a dll or whether it's ok to have it in the main body of the code.
Any ideas? Thanks in advance.
PS. I'm using vc++ standard ed. version 4.00
