◆ server_mutex

Lock to prevent wl_display_dispatch / wl_display_roundtrip / wl_display_flush from running at the same time.

Definition at line 340 of file GHOST_SystemWayland.hh.

◆ timer_mutex

std::mutex* GHOST_SystemWayland::timer_mutex = nullptr

Threads must lock this before manipulating GWL_Display::ghost_timer_manager.

Note: Using a separate lock to server_mutex is necessary because the server lock is already held when calling ghost_wl_display_event_pump. If manipulating the timer used the server_mutex, event pump can indirectly handle key up/down events which would lock server_mutex causing a dead-lock.
