Function Documentation

void dt_free_reader (  dt_reader *  obj  )

Destroy and free a dt_reader object. Definition at line 28 of file dt_stream_base.c.

void dt_free_writer (  dt_writer *  obj  )

Destroy and free a dt_writer object. Definition at line 53 of file dt_stream_base.c.

void dt_init_reader_base (  dt_reader *  reader, void(*  free_impl)(dt_reader *), dt_bool(*  read_impl)(dt_reader *, dt_stream_step *) )

Definition at line 65 of file dt_stream_base.c.

void dt_init_writer_base (  dt_writer *  writer, void(*  free_impl)(dt_writer *), dt_bool(*  write_impl)(dt_writer *, dt_stream_step const *) )

Definition at line 77 of file dt_stream_base.c.

dt_bool dt_read (  dt_reader *  obj, dt_stream_step *  step )

Retrieve a streaming step from obj into step. This is a polymorphic function, which will use a subclass-specific forwarding function stored within the object. Returns: A non-zero value if the operation was successful. Definition at line 19 of file dt_stream_base.c.

dt_bool dt_write (  dt_writer *  obj, dt_stream_step const *  step )

Transmit the streaming step in step to obj. This is a polymorphic function, which will use a subclass-specific forwarding function stored within the object. Returns: A non-zero value if the operation was successful. Definition at line 44 of file dt_stream_base.c.
