hid_set_nonblocking method
@brief Set the device handle to be non-blocking.
In non-blocking mode calls to hid_read() will return immediately with a value of 0 if there is no data to be read. In blocking mode, hid_read() will wait (block) until there is data to read before returning.
Nonblocking can be turned on and off at any time.
@ingroup API @param dev A device handle returned from hid_open(). @param nonblock enable or not the nonblocking reads
- 1 to enable nonblocking
- 0 to disable nonblocking.
@returns This function returns 0 on success and -1 on error. Call hid_error(dev) to get the failure reason.
