View the official Windows Driver Kit DDI referenceNo description available.
The KsMethodHandler function handles methods requested through IOCTL_KS_METHOD. It works with all method identifiers defined by the sets. The function can only be called at PASSIVE_LEVEL.
Irp [in]Specifies the IRP with the method request being handled.
MethodSetsCount [in]Indicates the number of method set structures being passed.
MethodSet [in]Specifies the pointer to the list of method set information.
The KsMethodHandler function returns STATUS_SUCCESS if successful, or an error specific to the method being handled if unsuccessful. The function always sets the IO_STATUS_BLOCK.Information field of the PIRP.IoStatus element within the IRP to zero because of an internal error, unless the element is set by a method handler. The function does not set the IO_STATUS_BLOCK.Status field nor complete the IRP.
The owner of a method set can perform prefiltering or postfiltering of the method handling using the KsMethodHandler and KsFastMethodHandler functions.
