video_displaydescr(3)		  Arcan Lua API 	   video_displaydescr(3)

NAME
     video_displaydescr  -  retrieve  a  byte block and a hash for identifying a
     specific display

SYNOPSIS
     string:block, string:hash, table:metadata
     video_displaydescr( int:dispid )

DESCRIPTION
     For dealing with multiple-monitors where one might need to track  settings,
     calibration  and other monitor individual properties, some kind of identity
     token is needed. This function returns the platform identity one, which for
     most cases should be an EDID  formatted binary  blob,  along  with  a  hash
     value  of	the  contents  of the block for when user-readable names are not
     needed but a (hopefully) unique identifier is.

     If the platform is capable of parsing the block, higher  level  information
     may be available via the returned metadata  table. These are display, plat-
     form  and	OS   dependent. Possible keys include: 'error', 'make', 'model',
     'serial'.

EXAMPLE
     function video_displaydescr0()
	   warning( video_displaydescr(0) );
     end
