NAMEdisplay-multi - Duplicate visual operations onto multiple visuals
SYNOPSISdisplay-multi <:targetspec> ...
DESCRIPTIONDuplicates all drawing operations onto multiple child targets, thus producing identical output on multiple visuals.
OPTIONSThe argument to display-multi is a colon- (:) separated list of target specs to draw on. Because target specs can (and often do) contain colons, they need to be enclosed in parentheses. target-spec Specifies the target which to draw on (the parent target). This defaults to automatic selection (just like using ggiOpen(NULL) when GGI_DISPLAY is not set).
FEATURESo DirectBuffer never supported. o Unaccelerated. DISPLAY-MULTI(7)
