RxUsbDataTransfer

Description
Executes synchronous Bulk or Interrupt Transfer with a specific endpoint.

Syntax
rc = RxUsbDataTransfer(Handle,Endpoint,AltSetting,NumBytes,Data,Timeout,Flags)

Parameters

 * Handle : the Device Handle received from the previous RxUsbOpen.


 * Endpoint : the Endpoint Number appropriate for the data transfer.


 * AltSetting : the Alternate Setting of the interface having this endpoint.


 * Timeout : the timeout to wait for completion in milliseconds.


 * Flags : use 1 to transfer all data or 0 to allow less transferred.

For device-to-host data transfer:


 * NumBytes : the number of bytes to be transferred or 0 for no data transfer.


 * Data : the name of the variable to receive the data bytes transferred.

For host-to-device data transfer:


 * NumBytes : the name of the variable to receive the number of bytes transferred.


 * Data : the character string if any with the data bytes to be transferred.

Return Code
0x0000 - NO_ERROR
