The KMCL_SERVER_ONLY_METHODS structure contains function pointers for server-only functions for the VMBus Kernel Mode Client Library (KMCL) interface.
For more information about how to access the KMCL interface, see the Remarks section.
VmbChannelMapGpadlA pointer to the VmbChannelMapGpadl function.
VmbChannelRestoreFromBufferA pointer to the VmbChannelRestoreFromBuffer function.
VmbChannelSaveBeginA pointer to the VmbChannelSaveBegin function.
VmbChannelSaveContinueA pointer to the VmbChannelSaveContinue function.
VmbChannelSaveEndA pointer to the VmbChannelSaveEnd function.
VmbChannelUnmapGpadlA pointer to the VmbChannelUnmapGpadl function.
VmbConvertVmbusHandleToKernelHandleA pointer to the VmbConvertVmbusHandleToKernelHandle function.
VmbPacketRestoreA pointer to the VmbPacketRestore function.
VmbServerChannelInitSetFlagsA pointer to the VmbServerChannelInitSetFlags function.
VmbServerChannelInitSetMmioMegabytesA pointer to the VmbServerChannelInitSetMmioMegabytes function.
VmbServerChannelInitSetSaveRestorePacketCallbacksA pointer to the VmbServerChannelInitSetSaveRestorePacketCallbacks function.
VmbServerChannelInitSetTargetInterfaceIdA pointer to the VmbServerChannelInitSetTargetInterfaceId function.
VmbServerChannelInitSetTargetVtlA pointer to the VmbServerChannelInitSetTargetVtl function.
VmbServerChannelInitSetVmbusHandleA pointer to the VmbServerChannelInitSetVmbusHandle function.
The function pointers in KMCL_SERVER_ONLY_METHODS are called through the VMBus Kernel Mode Client Library (KMCL) interface, provided by the Vmbkmcl.sys bus driver. This structure contains function pointers for server-only functions.
To access both client and server-only functions of the KMCL interface, allocate a KMCL_SERVER_INTERFACE_V1 structure to receive the interface, then call either WdfFdoQueryForInterface or WdfIoTargetQueryForInterface with these parameters:
sizeof(KMCL_SERVER_INTERFACE_V1)The KMCL_SERVER_INTERFACE_V1 structure is defined as follows for C language code:
typedef struct _KMCL_SERVER_INTERFACE_V1 {
KMCL_CLIENT_INTERFACE_V1;
KMCL_SERVER_ONLY_METHODS;
} KMCL_SERVER_INTERFACE_V1, *PKMCL_SERVER_INTERFACE_V1;
If the interface query function succeeds, the KMCL_SERVER_INTERFACE_V1 structure contains both a KMCL_CLIENT_INTERFACE_V1 structure and a KMCL_SERVER_ONLY_METHODS structure. The KMCL_SERVER_ONLY_METHODS structure contains function pointers that you can use to call VMBus KMCL server-only functions.
For KMCL client methods, see the KMCL_CLIENT_INTERFACE_V1 structure.
