All Implemented Interfaces:
AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
public class OpenHow extends org.lwjgl.system.Struct<OpenHow> implements org.lwjgl.system.NativeResource
Arguments for how openat2(2) should open the target path.

If only flags and @mode are non-zero, then openat2(2) operates very similarly to openat(2).

However, unlike openat(2), unknown or invalid bits in flags result in -EINVAL rather than being silently ignored. mode must be zero unless one of FCNTL.O_CREAT, FCNTL.O_TMPFILE are set.
