Description
Executes the Standard Device Request that clears or disables an interface feature.
Syntax
rc = RxUsbInterfaceClearFeature(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 0xFF0D - ERROR_INVALID_DATA 0xFF13 - ERROR_I24_INVALID_PARAMETER 0xFF13 - USB_IDC_PARMERR 0xFF18 - USB_IDC_ADDRINV 0xFF37 - ERROR_DEV_NOT_EXIST 0xFF5D - EROR_NO_ITEMS 0xFFA7 - ERROR_LOCK_FAILED
Remarks
Example Code
/* add RxUsbInterfaceClearFeature */
rc = RxFuncAdd('RxUsbInterfaceClearFeature','usbcalls','RxUsbInterfaceClearFeature')
say '+RxUsbInterfaceClearFeature(),RC=0x'd2x(rc)
/* invoke RxUsbInterfaceClearFeature */
Interface=1 /* second interface number */
Feature=0 /* feature selector to clear */
rc = RxUsbInterfaceClearFeature(Handle,Interface,Feature)
say '*RxUsbInterfaceClearFeature(),RC=0x'd2x(rc)
/* drop RxUsbInterfaceClearFeature */
rc = RxFuncDrop('RxUsbInterfaceClearFeature')
say '-RxUsbInterfaceClearFeature(),RC=0x'd2x(rc)
