Can this be used to exit from a route block to avoid the workaround using flags, e.g.:
route { route(1); if (retcode == 99) break; ... }
route[1] { if (security check fails) { return(99); } ... do some things; }
Is there a differnce between return(0); and break; ?

Hello,
there is a new variable in configuration file 'retcode' that can be used to test against an integer the value returned by last invoked function or route. In the case of routes that uses return, it is the returned value. The changes were done yesterday, so the pserver CVS head is now synchronized.
It is similar to $? from bash ($? can be used also in configuration file, having the same meaning as 'retcode'). Take care when you are testing this value, it can be easily misleading. For example:
route[1] { if(method=="INVITE") return(1); return(2); }
route {
route(1); if(retcode==2) { log("The request is a REGISTER\n"); }; if(retcode==1) { ... };}
In case of REGISTER, the 'log' function is executed and the value of retcode is changed. The proper scripting is: route {
route(1); if(retcode==2) { log("The request is a REGISTER\n"); } else if(retcode==1) { ... };}
I have updated the docuwiki for 'return()' and added 'retcode' there, too.
