asterisk users - Nov 2007 - use dial plan passed arg value in C agi code

Hello * users,

I know that passing variable in the AGI script is by

exten => _.,1,AGI(simple_c_prgm|123|789)  ; 123, 789 are arguments being
passed and simple_c_prgm is C code

Now how will I receive these variables within C code ? Is it by the same way
arguments are passed in command line to C by using argc and argv or there is
more to be done than that?

Thanks

Regards

Asterisk used to NOT support more than one arg to an AGI.  I thought 
this was fixed in 1.2, but since I now use dialplan variables to pass 
data to AGIs, I don't know if it really was fixed or not.

Sadly those docs cover the situation of this:

   exten => 666,1,Set(MY_VAR=fred)
   exten => 666,n,AGI(simple_c_prgm)

Not this:
   exten => 666,1,AGI(simple_c_prgm|123|789)
