枚举系统中的所有设备驱动程序

以下示例代码使用 EnumDeviceDrivers 函数枚举系统中的当前设备驱动程序。 它将从此函数调用中检索到的加载地址传递给 GetDeviceDriverBaseName 函数，以检索可显示的名称。

#include <windows.h>
#include <psapi.h>
#include <tchar.h>
#include <stdio.h>

// To ensure correct resolution of symbols, add Psapi.lib to TARGETLIBS
// and compile with -DPSAPI_VERSION=1

#define ARRAY_SIZE 1024

int main( void )
{
   LPVOID drivers[ARRAY_SIZE];
   DWORD cbNeeded;
   int cDrivers, i;

   if( EnumDeviceDrivers(drivers, sizeof(drivers), &cbNeeded) && cbNeeded < sizeof(drivers))
   { 
      TCHAR szDriver[ARRAY_SIZE];

      cDrivers = cbNeeded / sizeof(drivers[0]);

      _tprintf(TEXT("There are %d drivers:\n"), cDrivers);      
      for (i=0; i < cDrivers; i++ )
      {
         if(GetDeviceDriverBaseName(drivers[i], szDriver, sizeof(szDriver) /              sizeof(szDriver[0])))
         {
            _tprintf(TEXT("%d: %s\n"), i+1, szDriver);
         }
      }
   }
   else 
   {
        _tprintf(TEXT("EnumDeviceDrivers failed; array size needed is %d\n"),             cbNeeded / sizeof(LPVOID));
        return 1;
   }

return 0;
}
