> This section describes audio-enabling macros and the high-level service routines designed to simplify writing macros.
> 
> The service routines are valuable for many applications and are needed for information presentation 
>  facility (IPF) support. 
> 
> The five functions (high-level service API) are:
> 
> mciPlayFile,
> mciRecordAudioFile,
> mciPlayResource,
> mmioFindElement, and
> mmioRemoveElement.
> 
> These functions are located in MCIAPI.DLL. Define INCL_MACHDR and 
> include OS2ME.H in any source that needs access to the high-level service API.
> 
> The OS/2 Multimedia Programming 
> Reference provides a detailed description of these functions. 
> 
> Note:  These functions are also provided as 16-bit functions. The 16-bit functions include "16" in the function name as follows: 
> 
> o  mci16PlayFile
> o  mci16PlayResource
> o  mci16RecordAudioFile
> o  mmio16FindElement
> o  mmio16RemoveElement
> 
> 
> The mciPlayFile function plays a multimedia file or waveaudio bundle element without displaying a device 
> control panel.
> 
> ************************************************************************!!
> 
> The mciPlayResource function operates much the same as mciPlayFile, except that it plays the multimedia object that is stored in a program resource and is intended for IPF support, not audio macros.
> 
> ************************************************************************!!
> 
> The function loads the resource using DosGetResource, creates a MMIO memory file, and opens the default device to play the memory file. 
> 
> The mciRecordAudioFile function provides a very simple recorder window allowing the recording of audio notations.
> 
> The mciRecordAudioFile function does not return until the recording is complete and the window is closed.
> 
> This function creates the file if it does not exist.The mciRecordAudioFile records digital audio data from the microphone input of the default waveaudio device.
> 
> When the file is initially created the settings are PCM, 11 kHz, mono, and the default sample size of the
> audio adapter in use.
> 
> All play and record operations are 
> performed from beginning to end. 
> 
> The mmioRemoveElement function removes an element from a compound file and the mmioFindElement function enumerates elements in a compound file.
> 
> For more information on the compound file structure, see RIFF Compound File Overview.
