This is useful for VST3 plugins that host other VST3 plugins. In this scenario, the 'inner'
|
||
|
|
plugin may want to register additional file descriptors on top of those registered by the
|
||
|
|
'outer' plugin. In order for this to work, the outer plugin must in turn pass this request
|
||
|
|
on to the host, to indicate that the outer plugin wants to receive FD callbacks for both the
|
||
|
|
inner and outer plugin.
