Data Structures

	IPC scan processes results. More...
struct	WDS_IPC_MSG_RX
	IPC message received. More...

Macros
#define	WDS_SharedBufferGetGlobalHandle(pKerBuf)   ((pKerBuf)->hKerBuf)
	Utility macro that returns a kernel buffer global handle that can be used for buffer sharing between multiple processes.

Typedefs
typedef void(*	IPC_MSG_RX_HANDLER) (_In_ WDS_IPC_MSG_RX *pIpcRxMsg, _In_ void *pData)
	WinDriver IPC message handler callback.

Functions
BOOL DLLCALLCONV	WDS_IsIpcRegistered (void)
	Enables the application to check if it is already registered with WinDriver IPC.
DWORD DLLCALLCONV	WDS_IpcRegister (_In_ const CHAR *pcProcessName, _In_ DWORD dwGroupID, _In_ DWORD dwSubGroupID, _In_ DWORD dwAction, _In_ IPC_MSG_RX_HANDLER pFunc, _In_ void *pData)
	Registers an application with WinDriver IPC.
void DLLCALLCONV	WDS_IpcUnRegister (void)
	This function enables the user application to unregister with WinDriver IPC.
DWORD DLLCALLCONV	WDS_IpcScanProcs (_Outptr_ WDS_IPC_SCAN_RESULT *pIpcScanResult)
	Scans and returns information of all registered processes that share the application process groupID (as was given to WDS_IpcRegister() or a specific groupID.)
DWORD DLLCALLCONV	WDS_IpcUidUnicast (_In_ DWORD dwRecipientUID, _In_ DWORD dwMsgID, _In_ UINT64 qwMsgData)
	Sends a message to a specific process with WinDriver IPC unique ID.
DWORD DLLCALLCONV	WDS_IpcSubGroupMulticast (_In_ DWORD dwRecipientSubGroupID, _In_ DWORD dwMsgID, _In_ UINT64 qwMsgData)
	Sends a message to all processes that registered with the same sub-group ID.
DWORD DLLCALLCONV	WDS_IpcMulticast (_In_ DWORD dwMsgID, _In_ UINT64 qwMsgData)
	Sends a message to all processes that were registered with the same group ID as the sending process.
DWORD DLLCALLCONV	WDS_SharedBufferAlloc (_In_ UINT64 qwBytes, _In_ DWORD dwOptions, _Outptr_ WD_KERNEL_BUFFER **ppKerBuf)
	Allocates a memory buffer that can be shared between the user mode and the kernel mode ("shared buffer"), and returns user-mode and kernel-mode virtual address space mappings of the allocated buffer.
DWORD DLLCALLCONV	WDS_SharedBufferGet (_In_ DWORD hKerBuf, _Outptr_ WD_KERNEL_BUFFER **ppKerBuf)
	Retrieves a shared buffer which was allocated by another process.
DWORD DLLCALLCONV	WDS_SharedBufferFree (_In_ WD_KERNEL_BUFFER *pKerBuf)
	Frees a shared buffer that was allocated by a previous call to WDS_SharedBufferAlloc().
DWORD DLLCALLCONV	WDS_SharedIntEnable (_In_ const CHAR *pcProcessName, _In_ DWORD dwGroupID, _In_ DWORD dwSubGroupID, _In_ DWORD dwAction, _In_ IPC_MSG_RX_HANDLER pFunc, _In_ void *pData)
	Enables the shared interrupts mechanism of WinDriver.
DWORD DLLCALLCONV	WDS_SharedIntDisableGlobal (void)
	Disables the Shared Interrupts mechanism of WinDriver for all processes.
DWORD DLLCALLCONV	WDS_SharedIntDisableLocal (void)
	Disables the Shared Interrupts mechanism of WinDriver for the current process.
BOOL DLLCALLCONV	WDS_IsSharedIntsEnabledLocally (void)
	Check and returns whether shared interrupts are enabled for the current process.
