Description
Executes the Standard Device Request that sets or enables an endpoint feature.
Syntax
rc = RxUsbEndpointSetFeature(Handle,Endpoint,Feature)
Parameters
- Handle
- the Device Handle received from the previous RxUsbOpen.
- Endpoint
- the specific Endpoint Number appropriate for the USB device.
- Feature
- the Feature Selector appropriate for the endpoint.
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 RxUsbEndpointSetFeature */
rc = RxFuncAdd('RxUsbEndpointSetFeature','usbcalls','RxUsbEndpointSetFeature')
say '+RxUsbEndpointSetFeature(),RC=0x'd2x(rc)
/* invoke RxUsbEndpointSetFeature */
Endpoint=0 /* default control endpoint */
Endpoint=128+1 /* isochronous endpoint */
Feature=0 /* feature selector to be set */
rc = RxUsbEndpointSetFeature(Handle,Endpoint,Feature)
say '*RxUsbEndpointSetFeature(),RC=0x'd2x(rc)
/* drop RxUsbEndpointSetFeature */
rc = RxFuncDrop('RxUsbEndpointSetFeature')
say '-RxUsbEndpointSetFeature(),RC=0x'd2x(rc)
