Function Documentation

int ftdi_readstream (struct ftdi_context * ftdi, FTDIStreamCallback * callback, void * userdata, int packetsPerTransfer, int numTransfers)

Streaming reading of data from the device

Use asynchronous transfers in libusb-1.0 for high-performance streaming of data from a device interface back to the PC. This function continuously transfers data until either an error occurs or the callback returns a nonzero value. This function returns a libusb error code or the callback's return value.

For every contiguous block of received data, the callback will be invoked.

Parameters

ftdi pointer to ftdi_context
callback to user supplied function for one block of data
userdata
packetsPerTransfer number of packets per transfer
numTransfers Number of transfers per callback
