=head3 route_request
|
|
|
|
This subroutine is used for the command called from genesis. As the client of
|
|
genesis is not a command line interface, this hook comand can help save one
|
|
fork compare with a common command.
|
|
|
|
return REQUEST_UPDATE if request is received.
|
|
return REQUEST_ERROR if error happens.
|
|
|
|
Usage example:
|
|
This is a hook function in xcatd, do not use it directly.
