classifyFn

classifyFn

The filter engine calls a callout driver's classifyFn function whenever there is data to be processed by the callout driver. There are three prototypes for the classifyFn function:

  • For the classifyFn function prototype that's supported starting with Windows Vista, see classifyFn0.

  • For the classifyFn function prototype that's supported starting with Windows 7, see classifyFn1. You must use this prototype if your callout driver uses WFP features that aren't supported in earlier Windows versions.

  • For the classifyFn function prototype that's supported starting with Windows 8, see classifyFn2. You must use this prototype if your callout driver uses WFP features that aren't supported in earlier Windows versions.
