#722 closed bug (fixed)

usb_hid uses undocumented cbuf API

Reported by: mmlr Owned by: korli

Platform: All


The usb_hid input driver uses an undocumented cbuf kernel API on R5 (see src/add-ons/kernel/drivers/input/usb_hid/hid.h). This API is different from the cbuf implementation that is present in the Haiku kernel. It is therefore not possible to build the usb_hid driver with TARGET_PLATFORM=haiku. I defined the following to get it to build:

#define cbuf_init cbuf_get_chain #define cbuf_delete cbuf_free_chain #define cbuf_putn(x, y, z) cbuf_memcpy_to_chain(x, 0, y, z) #define cbuf_getn(x, y, z) cbuf_memcpy_from_chain(x, 0, y, z)

But I highly doubt that it is correct. Especially the cbuf_putn/cbuf_getn which probably should increment/decrement some position variable.
