Export drm RDWR/CLOEXEC flags #182

Closed cmeissl closed 9 months ago

cmeissl commented 9 months ago

The drm headers define:

#define DRM_RDWR O_RDWR
#define DRM_CLOEXEC O_CLOEXEC

These can be passed to prime_handle_to_fd and should be exported by the drm crate.

This isn't strictly necessary since those should always be the same as the variants from libc, but it could be handy to just have drm::CLOEXEC and drm::RDWR.

These may differ by OS/architecture (looking at libc, O_CLOEXEC is different on some Linux architectures?), so they can be defined using linux-raw-sys on Linux and libc elsewhere. Matching rustix and how drm-sys defines __kernel_size_t.
