  • Field Details

    • SIZEOF

      public static final int SIZEOF
      The struct size in bytes.

    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.

    • IOV_BASE

      public static final int IOV_BASE
      The struct member offsets.

    • IOV_LEN

      public static final int IOV_LEN
      The struct member offsets.

  • Constructor Details

    • IOVec

      public IOVec(ByteBuffer container)
      Creates a IOVec 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.

  • Method Details

    • sizeof

      public int sizeof()
      Description copied from class: Struct
      Returns sizeof(struct).
      Specified by:
      sizeof in class Struct<IOVec>

    • iov_base

      public @Nullable ByteBuffer iov_base()
      Returns:
      a ByteBuffer view of the data pointed to by the iov_base field.

    • iov_len

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

    • iov_base

      public IOVec iov_base(@Nullable ByteBuffer value)
      Sets the address of the specified ByteBuffer to the iov_base field.

    • iov_len

      public IOVec iov_len(long value)
      Sets the specified value to the iov_len field.

    • set

      public IOVec set(@Nullable ByteBuffer iov_base, long iov_len)
      Initializes this struct with the specified values.

    • set

      public IOVec set(IOVec src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
      this struct

    • malloc

      public static IOVec malloc()
      Returns a new IOVec instance allocated with memAlloc. The instance must be explicitly freed.

    • calloc

      public static IOVec calloc()
      Returns a new IOVec instance allocated with memCalloc. The instance must be explicitly freed.

    • create

      public static IOVec create()
      Returns a new IOVec instance allocated with BufferUtils.

    • create

      public static IOVec create(long address)
      Returns a new IOVec instance for the specified memory address.

    • createSafe

      public static @Nullable IOVec createSafe(long address)
      Like create, but returns null if address is NULL.

    • malloc

      public static IOVec.Buffer malloc(int capacity)

      Returns a new IOVec.Buffer instance allocated with BufferUtils.
      Parameters:
      capacity - the buffer capacity

    • create

      public static IOVec.Buffer create(long address, int capacity)
