ListDisplays

Takes a type-0x6 output buffer containing the array of #DisplayInfo output entries. Returns an output u64.

OpenDisplay

Takes a #DisplayName as input. Returns an output u64, the DisplayId.

To open the default display, input string "Default" can be used.

OpenDefaultDisplay

Returns an output u64.

Probably not (?) used by newer official user-processes, since those use OpenDisplay with the default string instead.

CloseDisplay

Takes an input u64, DisplayId.

SetDisplayEnabled

Takes an input u32 boolean, and an u64(DisplayId?).

GetDisplayResolution

Takes an input u64 DisplayId and returns two output u64s.

OpenLayer

Takes a PID-descriptor, an type-0x6 buffer, a #DisplayName, and two u64s. Returns an output u64.

CloseLayer

Takes an input u64.
