jaylink_device_handle struct

Device instance.

Buffer for write and read operations. Note that write and read operations are always processed consecutively and therefore the same buffer can be used for both.

Buffer size.

Number of bytes left for the read operation.

Number of bytes available in the buffer to be read.

Current read position in the buffer.

Number of bytes left to be written before the write operation will be performed.

Current write position in the buffer. This is equivalent to the number of bytes in the buffer and used for write operations only.

Socket descriptor. This field is used for devices with host interface #JAYLINK_HIF_TCP only.
