16.9.1. Return Values
Returning values from the command functions have a special meaning in the
configuration file. The command functions return an integer value, and the
config file interpreter use it as follows:
- if <0 - evaluation of the return code is FALSE
- if 0 - the interpreter stop executing the configuration file
- if >0 - evaluation of the return code is TRUE

So what about if I want to develop a module function which can return 0 as a
valid integer and store it in a pv? (i.e. a function returning the number of
locations for a given AoR).
It seems that
allow_source_address_group() behaves as "return(0)" when
the returned value is 0. But this is not documented and IMHO it cannot be
the expected behavior, am I right?
You mean 'return 0' is not documented or this particular function's
behavior with group id 0?
"return 0" is document (AFAIK) but I didn't expect that any function
returning
0 means "exiting".
Also, in the current module (permissions) and current function
(allow_source_address_group) this is a limitation as it doesn't allow
returning a group value 0.
Thanks.
