Function Documentation

sternum_port_transmit()

signed long int sternum_port_transmit	(	const void *	data,
		size_t	count
	)

Sternum's port to write to the communication channel.

Parameters

data	The data to be transmitted.
count	The size of the data to be transmitted.

Note

It is expected from this function to send all of the data in a single call.

If it's necessary to divide data into smaller chunks for reliable transmission, it should be implemented internally in this port.

If the returned value of sent bytes is different than count, then the transmission will be considered as a failure.

Returns

The amount of bytes sent on success and -1 on failure.
