Header file

Defined in SDL3/SDL_hints.h

Overview

SDL might open something like "/dev/dri/cardNN" to access KMSDRM functionality, where "NN" is a device index number. SDL makes a guess at the best index to use (usually zero), but the app or user can set this hint to a number between 0 and 99 to force selection.

This hint should be set before SDL is initialized.
