◆ WD_KernelPlugInCall

#define WD_KernelPlugInCall (   h,
  pKernelPlugInCall 
)
Value:
WD_FUNCTION(IOCTL_WD_KERNEL_PLUGIN_CALL, h, pKernelPlugInCall, \
#define FALSE
Definition: kpstdlib.h:260
#define IOCTL_WD_KERNEL_PLUGIN_CALL
Definition: windrvr.h:1625
#define WD_FUNCTION
Definition: windrvr.h:1843

Calls a routine in the Kernel PlugIn to be executed.

Parameters
[in]hHandle to WinDriver's kernel-mode driver as received from WD_Open()
[in,out]pKernelPlugInCallPointer to Kernel PlugIn information structure
Returns
Returns WD_STATUS_SUCCESS (0) on success, or an appropriate error code otherwise
Remarks
Calling the WD_KernelPlugInCall() function in the user mode will call your KP_Call callback function in the kernel. The KP_Call Kernel PlugIn function will determine what routine to execute according to the message passed to it in the WD_KERNEL_PLUGIN_CALL structure.
BZERO (kpCall);
/* Prepare the kpCall structure from WD_KernelPlugInOpen(): */

the action performed in the kernel: */

kpCall.pData = &mydrv; /* The data to pass to the Kernel PlugIn */

const char *DLLCALLCONV Stat2Str(_In_ DWORD dwStatus)
Retrieves the status string that corresponds to a status code.
