Constant KMSDRM_DEVICE_INDEX

pub const KMSDRM_DEVICE_INDEX: &'static str;
Available on crate feature dep_sdl3 only.
Expand description

A variable that controls what KMSDRM device to use.

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.

§Availability

This hint is available since SDL 3.2.0.
