Summary

Functions

Called internally to initialize the draw_buf_handlers in lv_global

void lv_draw_buf_init_handlers(void)

TODO(v10): the draw buffer should describe its own storage well enough that the layer isn't needed. Merge this back into lv_draw_buf_clear() then.

void lv_draw_buf_clear_ex(lv_draw_buf_t *draw_buf, const lv_area_t *a, lv_layer_t *layer)
