3	*@@sourcefile syssound.c:
4	* this has code for querying and manipulating the
5	* system sounds, which are stored in MMPM.INI in
6	* the MMOS2 directory. Also, we have support for
7	* manipulating Warp 4 sound schemes in here too.
8	* This code works on Warp 3 also.
9	*
10	* Usage: All OS/2 programs.
11	*
12	* Some of this code used to be in XWorkplace's main\common.c,
13	* as far as the regular system sounds were concerned.
14	* However, all this code has been greatly reworked
15	* and extended with V0.9.0.
16	*
17	* <B>About system sound configuration data</B>
18	*
19	* The current system sounds are stored in ?:\MMOS2\MMPM.INI.
20	*
21	* These are the general flags in the "MMPM2_AlarmSoundsData"
22	* application:
23	*
24	* -- If "EnableSounds" is FALSE, all system sounds are disabled.
25	* This defaults to TRUE (tested).
26	*
27	* -- If "ApplyVolumeToAll" is TRUE, the same volume is used for
28	* all sounds. This defaults to FALSE (tested).
29	*
30	* -- If ApplyVolumeToAll is TRUE, "Volume" is used for the
31	* global volume. Otherwise, the individual sound volumes
32	* (below) will be used.
33	*
34	* "MMPM2_AlarmSounds" then has all the system sounds. The keys
35	* in that application are numerical indices, which are listed
36	* in syssound.h.
37	*
38	* Each sound data block in there consists of three elements:
39	*
40	+ soundfile#description#volume
41	*
42	* where "description" is what is listed in the "Sound" object.
43	* "volume" is only used when "ApplyVolumeToAll" (above) is FALSE.
44	*
45	* We have functions in this code file for decoding/setting this
46	* (sndParseSoundData, sndQuerySystemSound, sndWriteSoundData,
47	* sndSetSystemSound).
48	*
49	* By contrast (and for no real reason), Warp 4 stores the
50	* "sound schemes" in OS2SYS.INI. I stuck with that for compatibility,
51	* although this prevents several users from having different
52	* sound schemes. What the heck.
53	*
54	* Anyways, the "PM_SOUND_SCHEMES_LIST" application is a directory of
55	* schemes, which in turn point to other applications in OS2SYS.INI
56	* which have the actual sound scheme data. All these applications
57	* appear to start with "PM_SOUND_xxx" by convention.
58	*
59	* Note that as opposed to the sound data in MMPM.INI, only the
60	* sound file name is stored here (not the three elements as
61	* described above). We slightly extend that mechanism to add an
62	* additional volume data field after the first null byte. This
63	* allows the default WPSound object to still be able to read
64	* the sound scheme data (it apparently uses PrfQueryProfileString)
65	* while the XWorkplace sound object replacement (XWPSound) can
66	* still store volume data as well.
67	*
68	* I have created more functions in this code file to easily load and
69	* store sound schemes (sndDoesSchemeExist, sndCreateSoundScheme,
70	* sndLoadSoundScheme, sndDestroySoundScheme).
71	*
72	* Note: Version numbering in this file relates to XWorkplace version
73	* numbering.
