The following additional services are available to an application:
The media control interface uses the following functions for sending messages to control multimedia devices.

Note: To use the 16-bit versions of mciGetDeviceID, mciSendString, and mciGetErrorString, define INCL_16 in the source file using these functions. The 16-bit entry points provide 16-bit applications with the ability to use multimedia in the OS/2 environment. For example:
#define INCL_MCIOS2 #define INCL_16 #include <os2me.h>
