This is a TIPC interface so the command numbers are subtracted by 16.
This multiplexes several interfaces into a single session that can be acquired through [[#Applet_Manager_services|am]].

UserSession

This is a TIPC interface so the command numbers are subtracted by 16.

This multiplexes several interfaces into a single session that can be acquired through am.

No input/output.

Called directly after #CreateAdrawContext.

GetAdrawFrameBufferHandle

Unofficial name.

Takes an input u64. Returns an output u32 FrameBufferHandle.

Official software sends the Id obtained with GetFrameBufferInfo from adraw.

GetAdrawImageHandle

Unofficial name.

Takes seven input u64s, two input u16s and two input u32s. Returns an output u32 ImageHandle.

Official software sends 0x100000000 in the first u64, 0 in all remaining u64s, Width and Height in the two u16s, BlockCount int the first u32 and the FrameBufferHandle from GetAdrawFrameBufferHandle in the last u32.
