Value:

Typedef Documentation

typedef CMAPI CONFIGRET(* P_CM_Get_Device_ID_ExA)(IN DEVINST dnDevInst, OUT PTCHAR Buffer, IN ULONG BufferLen, IN ULONG ulFlags, IN HMACHINE hMachine)
 

Pointer to the CM_Get_Device_ID_Ex function. As this function is not supported on NT4, we have to dynamically get its address, because our driver would refuse to load on NT4 else.

Definition at line 59 of file parport.c.

typedef WINSETUPAPI BOOL(* P_SetupDiGetDeviceInfoListDetailA)(IN HDEVINFO DeviceInfoSet, OUT PSP_DEVINFO_LIST_DETAIL_DATA DeviceInfoSetDetailData)
 

Pointer to the SetupDiGetDeviceInfoListDetailA function. As this function is not supported on NT4, we have to dynamically get its address, because our driver would refuse to load on NT4 else.

Definition at line 67 of file parport.c.

typedef * PSETUPAPI
 

PSETUPAPI is a pointer to SETUAPI

Function Documentation

VOID CbmParportRestart (  VOID   )
