谁有时间写个GetLogicalDrivers使用的例子

[ttpps]

调用一下kernel32.DLL中GetLogicalDrivers
感谢了

The GetLogicalDrives function returns a 32-bit value that contains one bit for each drive letter currently in use. Bit zero represents drive A. The code given below looks at each bit up through bit 25 and prints out the corresponding drive letter for each bit that contains a one.



DWORD drives;

int x;

drives = GetLogicalDrives();

CString str;

str.Format("Logical drives on this machine:\n");

//cout << "Logical drives on this machine: ";



for (x=0; x<26; x++)

{

if (drives & 1!=0)

{



CString fmt;

char ch=(char)('A'+x);

fmt.Format("%c",ch);

str+=fmt;

}

drives = drives >> 1;

}

MessageBox(str);

１．头文件有些什么？
２．kernel32.DLL怎么引用的，如何找到GetLogicalDrives()的入口地址的？
３．我现在在学Ｃ＃对Ｃ＋＋的库使用的不是太多，所以该用些什么．Ｈ文件不是太了解！
４．下面是我在C++（ＶＣ６.０下　windows sp）的代码（ＡＰＩ高手有空帮忙看）：
#include<stdio.h>
#include<string.h>
#include<iostream.h>
#define DWORD unsigned int
int main()
{
DWORD drives;

int x;

[DllImport("kernel32.DLL", EntryPoint = "GetLogicalDrivers",SetLastError = true,CharSet=CharSet.Ansi)]
private bool DWORD GetLogicalDrives(void)

drives = GetLogicalDrives();


cout << drives;

return 0;
}
问题提示：error C2143: syntax error : missing ';' before '['　Error executing cl.exe.
