Static methods:

• public static Error create (out Data d)
  Create a new data buffer, returns Error Status Code.
• public static Error create_from_file (out Data d, string filename, int copy = 1)
  Create a new data buffer filled with the content of the file. COPY must be non-zero. For delayed read, please use create_from_fd or create_from stream instead.
• public static Error create_from_memory (out Data d, uint8[] buffer, bool copy)
  Create a new data buffer filled with SIZE bytes starting from BUFFER. If COPY is false, COPYING is delayed until necessary and the data is taken from the original location when needed. Returns Error Status Code.

Methods:

• public DataEncoding* get_encoding ()
  Get the encoding attribute of the buffer
• public ssize_t read (uint8[] buf)
  Read up to SIZE bytes into buffer BUFFER from the data object. Return the number of characters read, 0 on EOF and -1 on error. If an error occurs, errno is set.
• public string release_and_get_mem (out size_t len)
  Destroy the object and return a pointer to its content. It's size is returned in R_LEN.
• public long seek (long offset, int whence = 0)
  Set the current position from where the next read or write starts in the data object to OFFSET, relativ to WHENCE.
• public Error set_encoding (DataEncoding enc)
  Set the encoding attribute of the buffer to ENC
• public ssize_t write (uint8[] buf)
  Write up to SIZE bytes from buffer BUFFER to the data object. Return the number of characters written, or -1 on error. If an error occurs, errno is set.
