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