Retrieves the load address for each device driver in the system.
BOOL EnumDeviceDrivers( LPVOID *lpImageBase, DWORD cb, LPDWORD lpcbNeeded );
An array that receives the list of load addresses for the device drivers.
The size of the lpImageBase array, in bytes. If the array is not large enough to store the load addresses, the lpcbNeeded parameter receives the required size of the array.
The number of bytes returned in the lpImageBase array.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
To determine how many device drivers were enumerated by the call to
EnumDeviceDrivers, divide the resulting value in the lpcbNeeded parameter by
Starting with Windows 7 and Windows Server 2008 R2, Psapi.h establishes version numbers for the PSAPI functions. The PSAPI version number affects the name used to call the function and the library that a program must load.
If PSAPI_VERSION is 2 or greater, this function is defined as K32EnumDeviceDrivers in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as EnumDeviceDrivers in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32EnumDeviceDrivers.
Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as EnumDeviceDrivers. To ensure correct resolution of symbols, add Psapi.lib to the TARGETLIBS macro and compile the program with –DPSAPI_VERSION=1. To use run-time dynamic linking, load Psapi.dll.
For an example, see Enumerating all Device Drivers in the System.
