RxUsbBulkRead

Executes synchronous device-to-host Bulk Transfer with a specific endpoint.

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

Parameters

 * Handle : the Device Handle received from the previous RxUsbOpen.
 * Endpoint : the Endpoint Number with the Direction Bit set to one.
 * AltSetting : the Alternate Setting of the interface having this endpoint.
 * 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.
 * Timeout : the timeout to wait for completion in milliseconds.

Return Code
0x0000 - NO_ERROR

/* invoke RxUsbBulkRead */ drop Data /* receives string of data bytes read */ Endpoint=128+1; AltSetting=0; NumBytes=4096; Timeout=8000 rc = RxUsbBulkRead(Handle,Endpoint,AltSetting,NumBytes,Data,Timeout) say '*RxUsbBulkRead,RC=0x'd2x(rc)

/* drop RxUsbBulkRead */ rc = RxFuncDrop('RxUsbBulkRead') say '-RxUsbBulkRead,RC=0x'd2x(rc)
