  • Constructor Details

    • EpollData

      public EpollData(ByteBuffer container)
      Creates a EpollData instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

    • u64

      public long u64()
      Returns:
      the value of the u64 field.

    • ptr

      public EpollData ptr(long value)
      Sets the specified value to the ptr field.

    • fd

      public EpollData fd(int value)

      Parameters:
      src - the source struct
      Returns:
      this struct
