Member Function Documentation

virtual void Dashel::FileDescriptorStream::flush (  )  [inline, virtual]

Flushes stream.

Calling this function requests the stream to be flushed, this may ensure that data is written to physical media or actually sent over a wire. The exact performed function depends on the stream type and operating system.

Implements Dashel::Stream.

Reimplemented in Dashel::SerialStream, Dashel::StdinStream, Dashel::StdoutStream, and Dashel::FileStream.

Definition at line 716 of file dashel-posix.cpp.

virtual void Dashel::FileDescriptorStream::read ( void *  data,
size_t  size 
) [inline, virtual]

Reads data from the stream.

Reads all requested data from the stream, blocking until all the data has been read, or some error occurs. Errors are signaled by throwing a DashelException exception, which may be caused either by device errors or reaching the end of file.

Parameters:
data Pointer to the memory where the read data should be stored.
size Amount of data to read in bytes.

Implements Dashel::Stream.

Reimplemented in Dashel::StdinStream, Dashel::StdoutStream, and Dashel::FileStream.

Definition at line 730 of file dashel-posix.cpp.

virtual bool Dashel::FileDescriptorStream::receiveDataAndCheckDisconnection (  )  [inline, virtual]

If necessary, read a byte and check for disconnection; return true on disconnection, fales otherwise.

Implements Dashel::SelectableStream.

Definition at line 769 of file dashel-posix.cpp.

virtual void Dashel::FileDescriptorStream::write ( const void *  data,
const size_t  size 
) [inline, virtual]

Write data to the stream.

Writes all requested data to the stream, blocking until all the data has been written, or some error occurs. Errors are signaled by throwing a DashelException exception. This function does not flush devices, therefore the data may not really have been written on return, but only been buffered. In order to flush the stream, call flush().

Parameters:
data Pointer to the data to write.
size Amount of data to write in bytes.

Implements Dashel::Stream.

Reimplemented in Dashel::StdinStream, Dashel::StdoutStream, and Dashel::FileStream.
