Detailed Description

Request to process an out-of-band atomic update through an xkb_machine or xkb_state.

Used with xkb_state::xkb_state_update_synthetic() and xkb_machine::xkb_machine_process_synthetic() to atomically apply any combination of:

• Latched and locked modifier and layout changes (via components)
• Boolean keyboard control changes (via components)
• Parameterized keyboard control changes (via layout_policy)

A NULL pointer means “not set / no change”.

Note

This struct uses a size-based versioning; see Extensible structure ABI contract for further details.
