Syntax
rc = RxUsbQueryVersion(DLLMajor,DLLMinor,USBMajor,USBMinor)
Parameters
- DLLMajor
- receives the usbcalls.dll major version.
- DLLMinor
- receives the usbcalls.dll minor version.
- USBMajor
- receives the usbresmg.sys major version.
- USBMinor
- receives the usbresmg.sys minor version.
Return Code
0x0000 - NO_ERROR
Errors
0x0057 - ERROR_INVALID_PARAMETER 0x1B58 - USB_NOT_INIT 0xFF13 - ERROR_I24_INVALID_PARAMETER 0xFF1F - ERROR_GEN_FAILURE 0xFF57 - ERROR_INVALID_PARAMETER
Example Code
/* add RxUsbQueryVersion */
rc = RxFuncAdd('RxUsbQueryVersion','usbcalls','RxUsbQueryVersion')
say '+RxUsbQueryVersion(),RC=0x'd2x(rc)
/* invoke RxUsbQueryVersion */
drop DLLMajor DLLMinor /* receives usbcalls version */
drop USBMajor USBMinor /* receives usbresmg version */
rc = RxUsbQueryVersion(DLLMajor,DLLMinor,USBMajor,USBMinor)
say '*RxUsbQueryVersion(),RC=0x'd2x(rc)
say 'USBCALLS 'DLLMajor'.'DLLMinor
say 'USBRESMG 'USBMajor'.'USBMinor

rc = RxFuncDrop('RxUsbQueryVersion')
say '-RxUsbQueryVersion(),
