在windows 2000下怎样将指定文件夹设置成共享

NET_API_STATUS NetShareAdd(
  LPWSTR servername,
  DWORD level,
  LPBYTE buf,
  LPDWORD parm_err
);

#include <stdio.h>

   struct share_info_50* pBuf = NULL;
   unsigned short cbBuffer;
   NET_API_STATUS nStatus;
   //

   //
   if ((argc < 3) || (argc > 4))
   {
      printf("Usage: %s [\\\\ServerName] ShareName SharePath\n", argv[0]);
      exit(1);
   }   if (argc == 4)
      pszServerName = argv[1];
   //

   //   share_info_50 structure.
   //
   cbBuffer = sizeof(struct share_info_50);
   pBuf = malloc(cbBuffer);   if (pBuf == NULL)
      printf("No memory\n");
   //
   // Assign values to the share_info_50 structure.
   //
   strcpy(pBuf->shi50_netname, argv[argc-2]);
   pBuf->shi50_type = STYPE_DISKTREE;

                         (char FAR *)pBuf,
                         cbBuffer);
   //
   // Display the result of the function call.
   //
   if (nStatus == NERR_Success)
      printf("Share added successfully\n");
   else
      fprintf(stderr, "A system error has occurred: %d\n", nStatus);
   //
   // Free the allocated memory.
   //
   if (pBuf != NULL)
      free(pBuf);   return 0;
}

直接使用MSDN中的例子有问题的。我修改了一些，才能用了，我把我的创建函数给你看看吧：

NetShareAdd(
  const char FAR * pszServer,
  short sLevel,
  const char FAR * pbBuffer,
  unsigned short  cbBuffer
);pszServer怎么用？我想设置本机的目录为共享，怎样做？

to hearttree(无心树) :
我的要在windows 2000下做，应该用SHARE_INFO_2吧？
to mfkzj() :
你的程序主要用的是哪几个函数？我都看糊涂了。为什么我用的netshareadd函数创建出新的文件夹。我的目的是将现有的本机文件夹变为共享文件夹。因该怎么做？？
上面的例子对么？不对应该怎样改？
