Description
This hook is called when the system needs to determine what domain to send a message to. It provides a way to set the gateway configuration directive at the per-message level.
This hook is called to determine which domain's queue messages should be placed in. The default queue is based on the result of config_get_binding_domain_gateway, but the queue can be overridden by registering a custom function at this hook. buff is supplied by the caller and is at least len bytes long. buff will be populated with the full gateway domain.
- closure
-
A pointer to the closure function.
- cs
-
For a description of this data type see generic_module_infrastructure.
- buff
-
The buffer for holding the routing domain.
- len
-
The length of the buffer.
This hook returns zero or 1. If non-zero, no further hook providers are called.
This hook will be called in any thread.
