[sr-dev] [SR-Users] using a pseudo-variable as a parameter to a module function

[Henning Westerholt]

(adding sr-dev list to CC)

Hi Michael,

small general addition - you are probably already aware of this 
documentation:

https://www.asipto.com/pub/kamailio-devel-guide/

There is work going on right now to update it, it needs also some 
extensions, e.g. for the PV core functions.

Cheers,

Henning
