Hi,

I have read in the docs about snd_asoundlib_version() to get a version string, 
but is there a way to get the SND_LIB_VERSION number from a runtime Alsa-lib, 
rather than from the header included at application build time, or would it 
have to be constructed from the string?

Thanks

Alan

No.

Why are you interested in the version number?  What are you actually
trying to check for?

To be able to apply workarounds for 'mis-behaviours' of older versions of 
Alsa-lib, since the aim (Portaudio) is to work as widely as possible.  A 
single number along the lines of SND_LIB_VERSION makes a one-line comparision 
possible - eg less than (1<<16 | 0 | 14) means prior to 1.0.14 - to activate 
some little fix-up.

Thanks

Alan
