[asterisk-users] 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
