read()

virtual int sl::IChannel::read ( void *  buffer, size_t  size  )

pure virtual

Read data from the chanel

Parameters

buffer	The buffer to receive data
size	The size of the read buffer

Returns

Bytes read (negative for read failure)

Implemented in sl::SerialPortChannel, sl::TcpChannel, and sl::UdpChannel.

waitForData()

virtual bool sl::IChannel::waitForData ( size_t  size, sl_u32  timeoutInMs = -1, size_t *  actualReady = nullptr  )

pure virtual

Wait for some data

Parameters

size	Bytes to wait
timeoutInMs	Wait timeout (in microseconds, -1 for forever)
actualReady	[out] actual ready bytes

Returns

true for data ready

Implemented in sl::SerialPortChannel, sl::TcpChannel, and sl::UdpChannel.

write()

virtual int sl::IChannel::write ( const void *  data, size_t  size  )

pure virtual

Send data to remote endpoint

Parameters

data	The data buffer
size	The size of data buffer (in bytes)

Returns

Bytes written (negative for write failure)

Implemented in sl::SerialPortChannel, sl::TcpChannel, and sl::UdpChannel.
