video_synchronization(3) Arcan Lua API video_synchronization(3) NAME video_synchronization - Get or set the current synchronization strategy SYNOPSIS nil or strtbl video_synchronization( string:strategy ) DESCRIPTION There are two stages for controlling synchronization strategy. The first one is static and can only be formed on the command-line, which should be limited to strategies that require specific video platform configuration that could invalidate the current graphics context. The other stage can be controlled using this function. First as a call with no arguments which will return a table with the set of allowed values. One of these values can then be used in a subsequent call which will switch the active strategy to the one specified, if possible. NOTES 1 The resulting strtbl values are valid only until the next call to set a video_synchronization. 2 Attempting to set an invalid or unknown synchronization will silently fail. No systemic state change will be attempted. 3 The returned strtbl is indexed both on name and by number. name in- dexes can be used to also get the short description of the strategy. 4 The available selection of synchronization strategies are video platform and possibly hardware configuration specific. EXAMPLE function video_synchronization0() local tbl = video_synchronization(); for k,v in ipairs(tbl) do print(v); print(tbl[v]); end if (#tbl > 0) then print("switching to " .. tbl[1]); video_synchronization(tbl[1]); else print("no dynamic synchronization strategies are available"); end end SEE ALSO: vidsys August 2026 video_synchronization(3)
