Hi,

I've talked with some people workiong on LSB about the possibility to put libasound as a part of the next LSB (surprisingly, they would like it more than I). I proposed that we should define the minimal set at first as the standard instead of taking all existing API functions.

An interesting input was that they did some statistics and counted the actual used functions/variables in ALSA API over distros. The data is attached below. I just put the number of apps and functions there to simplify. (It includes __* functions that are actaully internal ones, and I'm wondering why their numbers are so high. Anyway, they shouldn't be a part of standard.)

So, first, just take a look at it. You'll see how many functions are not actually used at all.

What I'd like to do now are:

- create a list of "standard" functions to be passed to LSB - clean up and actually drop some non-used functions - remove some functions from export list (in Versions file)

I'll try to create a list. Basically it'll be almost as same as the list of functions with count > 0, plus some related ones. Then, let's discuss and clean up...

BTW, regarding Versions. The versioned symbols for newly added functions seem not set properly as expected. We have entries

ALSA_0.9 { global: __snd_*; _snd_*; snd_*; local: *; };

and thus the rest functions after this all belong to ALSA_0.9 in the end (except for functions explicitly defined with obsolete macros in pcm.c). It means, we'll need to stick with ALSA_0.9 tag no matter which version is added. Only if the function API is changed and double definitions are needed, we'll tag to another version... Oh well.
