Function

CGEventSourceGetSourceStateID

Returns the source state associated with a Quartz event source.

Declaration

CGEventSourceStateID CGEventSourceGetSourceStateID(CGEventSourceRef source);

Parameters

source

The event source to access.

Return Value

The source state associated with the specified event source.

Discussion

This function returns the ID of the source state table associated with an event source.

For event sources created with the kCGEventSourceStatePrivate source state, this function returns the ID of the private source state table created for the event source. This unique ID may be passed to the CGEventSourceCreate function to create a second event source sharing the same state table. This may be useful, for example, in creating separate mouse and keyboard sources which share a common private state.
