N_int32 headIndex)

headIndex | Index of head to make active (GA_multiHeadType)

Description

This function is used to change the currently active output head for the device. Once the active head is changed, all calls to GetVideoModeInfo and SetVideoMode will be specific to the newly active head.

Note that by default device drivers that support multiple heads will usually default to gaActiveHeadClone mode, such that the same information will be display on all heads initially.
