为什么系统提示：Cannot open include file: 'dir.h': No such file or directory

函数名: findfirst, findnext
功能: 搜索磁盘目录; 取得下一个匹配的findfirst模式的文件
用法: int findfirst(char *pathname, struct ffblk *ffblk, int attrib);
int findnext(struct ffblk *ffblk);
程序例:

/* findnext example */

#include <stdio.h>
#include <dir.h>

int main(void)
{
struct ffblk ffblk;
int done;
printf("Directory listing of *.*\n");
done = findfirst("*.*",&ffblk,0);
while (!done)
{
printf(" %s\n", ffblk.ff_name);
done = findnext(&ffblk);
}

return 0;
}

WIN32_FIND_DATA find_data;
HANDLE search_handle;
search_handle = FindFirstFile( DirectoryPath,&find_data );
if (search_handle != INVALID_HANDLE_VALUE)
{
do
{
if (find_data.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY)
{
CString name = find_data.cFileName;
if( (name == ".")||(name == "..") )
continue;
}
}while(FindNextFile(search_handle,&find_data));

FindClose(search_handle);

MSDN里面的例子
用FindFirstFile

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

WIN32_FIND_DATA FileData;
HANDLE hSearch;
DWORD dwAttrs;
char szDirPath[] = "c:\\TEXTRO\\";
char szNewPath[MAX_PATH];
char szHome[MAX_PATH];

BOOL fFinished = FALSE;

// Create a new directory.

if (!CreateDirectory(szDirPath, NULL))
{
printf("Couldn't create new directory.");
return;
}

// Start searching for .TXT files in the current directory.

hSearch = FindFirstFile("*.txt", &FileData);
if (hSearch == INVALID_HANDLE_VALUE)
{
printf("No .TXT files found.");
return;
}

// Copy each .TXT file to the new directory
// and change it to read only, if not already.

while (!fFinished)
{
lstrcpy(szNewPath, szDirPath);
lstrcat(szNewPath, FileData.cFileName);
if (CopyFile(FileData.cFileName, szNewPath, FALSE))
{
dwAttrs = GetFileAttributes(FileData.cFileName);
if (!(dwAttrs & FILE_ATTRIBUTE_READONLY))
{
SetFileAttributes(szNewPath,
dwAttrs | FILE_ATTRIBUTE_READONLY);
}
}
else
{
printf("Couldn't copy file.");
return;
}

if (!FindNextFile(hSearch, &FileData))
{
if (GetLastError() == ERROR_NO_MORE_FILES)
{
MessageBox(hwnd, "No more .TXT files.",
"Search completed.", MB_OK);
fFinished = TRUE;
}
else
{
printf("Couldn't find next file.");
return;
}
}
}

// Close the search handle.

FindClose(hSearch);
