Functions In Win32

Hey, all.

Hope someone can make some useful suggestions, as i'm pretty much at a dead end!

I'm writing some code to run in a win32 envrionment, using the API to interface with audio hardware. At the moment this is very simple, and I'm pretty much just regurgitating micro$oft tutorials. I'm using the Bloodshed Dev-C++ compiler.

My problem is this -- i'm trying to use the CWaveFile class to provide a simple interface to .wav files. This class is defined in DSUtil.cpp, and makes use of the 'standard' mmio functions. To use these, I have to #include the mmsystem.h library, and link to the winmm.lib library; both of which I have done.

However -- when I try to compile, I get linker errors referring to the mmio functions, saying things like ' [Linker error] undefined reference to `mmioWrite@12''

I've no idea what else i'm supposed to link to/include; and there doesn't seem to be anything either on the web or on MSDN to clarify things further.

Anyone had any experience of this?

Best regards.

Hahaha. Sorry, I have no experience with that stuff, but
I think the problem here is you don't have a standard
version of the header or lib. Try getting another one and
replace your current DevC++ copy of the file.

Hope this could still be helpful to others out there. Here's what I did : I just included libwinmm.a from /DevC++/lib in the linker part of my "Project Options"

     exit(1); } What's the problem? The problem is that, CODE hd_ =

    Why? When the ....
