Description
Executes synchronous host-to-device Interrupt Transfer with a specific endpoint.
Syntax
rc = RxUsbIrqWrite(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 zero.
- AltSetting
- the Alternate Setting of the interface having this endpoint.
- 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.
- Timeout
- the timeout to wait for completion in milliseconds.
Return Code
0x0000 - NO_ERROR
Errors
0x0006 - ERROR_INVALID_HANDLE 0x0008 - ERROR_NOT_ENOUGH_MEMORY 0x0057 - ERROR_INVALID_PARAMETER 0x005F - ERROR_INTERRUPT 0x0122 - ERROR_TOO_MANY_HANDLES 0x0280 - ERROR_TIMEOUT 0x1B58 - USB_NOT_INIT 0x1B5B - USB_ERROR_INVALID_ENDPOINT 0x1B5C - USB_ERROR_LESSTRANSFERED 0x4000 - USB_IORB_REQUEST 0x80XX - USB_IORB_FAILED
Remarks
Example Code
/* add RxUsbIrqWrite */
rc = RxFuncAdd('RxUsbIrqWrite','usbcalls','RxUsbIrqWrite')
say '+RxUsbIrqWrite(),RC=0x'd2x(rc)
/* invoke RxUsbIrqWrite */
drop NumBytes /* receives number of data bytes written */
Endpoint=2; AltSetting=0; Data=copies(x2c(DB),4096); Timeout=8000
rc = RxUsbIrqWrite(Handle,Endpoint,AltSetting,NumBytes,Data,Timeout)
say '*RxUsbIrqWrite(),RC=0x'd2x(rc)
/* drop RxUsbIrqWrite */
rc = RxFuncDrop('RxUsbIrqWrite')
say '-RxUsbIrqWrite(),RC=0x'd2x(rc)
