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(last u64 is AppletResourceUserId). Returns an output u64.

CloseLayer

Takes an input u64.

CreateStrayLayer

Takes a type-0x6 buffer, an u32, and an u64. Returns two output u64s.

DestroyStrayLayer

Takes an input u64.

SetLayerScalingMode

Takes an input u32("ScalingMode") and u64.

GetIndirectLayerImageMap

Takes a PID-descriptor, an type-0x46 buffer, and four u64s(last u64 is AppletResourceUserId). Returns two output u64s.

GetIndirectLayerImageCropMap

Takes a PID-descriptor, an type-0x46 buffer, four floats, four u64s(last u64 is AppletResourceUserId). Returns two output u64s. The floats are stored immediately after each other(32bits).

GetIndirectLayerImageRequiredMemoryInfo

Takes two input u64s. Returns two output u64s.

GetDisplayVsyncEvent

Takes an input u64 DisplayId and returns a handle.
