Description
Executes the Standard Device Request that obtains the status of an endpoint.
Syntax
rc = RxUsbEndpointGetStatus(Handle,Endpoint,Status)
Parameters
- Handle
- the Device Handle received from the previous RxUsbOpen.
- Endpoint
- the specific Endpoint Number appropriate for the USB device.
- Status
- the name of the variable to receive the Endpoint Status.
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 0x4000 - USB_IORB_REQUEST 0x80XX - USB_IORB_FAILED
Remarks
Example Code
/* add RxUsbEndpointGetStatus */
rc = RxFuncAdd('RxUsbEndpointGetStatus','usbcalls','RxUsbEndpointGetStatus')
say '+RxUsbEndpointGetStatus(),RC=0x'd2x(rc)
/* invoke RxUsbEndpointGetStatus */
Endpoint=0 /* default control endpoint */
Endpoint=128+1 /* isochronous endpoint */
drop Status /* receives endpoint status */
rc = RxUsbEndpointGetStatus(Handle,Endpoint,Status)
say '*RxUsbEndpointGetStatus(),RC=0x'd2x(rc)
/* drop RxUsbEndpointGetStatus */
rc = RxFuncDrop('RxUsbEndpointGetStatus')
say '-RxUsbEndpointGetStatus(),RC=0x'd2x(rc)
