Detailed Description

Interface for managing DRM devices (/dev/dri/card*).

SRM provides this interface for opening and closing DRM devices.
Rather than relying solely on the open() and close() functions, you have the option to use libseat for enabling multi-session support.
You can refer to the srm-multi-session example to see how to enable multi-session support with libseat.
