Course OS2DD309 - OS/2 MM/2 Device Drivers

Objective

This five day workshop will enable programmers to write OS/2 MultiMedia Device Drivers (MM/2 DD); A MM/2 DD provides an easy to use programming interface for application developers interested in integrating MM functions into new or existing apps.

This workshop describes how the MM/2 DD communicates with the OS/2 kernel. I/O procs for media control (MIDI), Audio (wave and AMP/mixer) and video capture MM/2 drivers will be reviewed. Installation and debug techniques will also be covered. The Developer Connection Device Driver Kit (Devcon-DDK) will be used extensively in order to build and test the PDD.

Target Audience

IBM or OEM programmers who code device drivers for MM hardware, such as MIDI, audio, or video capture boards.

Attendee prerequisites

  • Programming expertise: C and/or MASM
  • Have written device drivers/utilities for OEM hardware (DOS device drivers, ROM BIOS, test utilities)

    • OS/2 2.x, OS/2 Warp
    • Developer Connection Device Driver Kit (Devcon-DDK)
