C盘下有一个a.exe的文件,用哪个API函数确认它是否存在硬盘上

TCAHR szFile[] = _T("c:\\a.exe");
if (_access(szFile, 00) == 0)
{
AfxMessageBox("文件存在");
}

函数定义如下：
int _access(
const char *path,
int mode
);
mode value Checks file for
00 Existence only
02 Write-only
04 Read-only
06 Read and write

咋这么懒涅，MSDN的东东，我给你贴上了！

CFileFind finder;
static const TCHAR szFileToFind[] = _T("C:\\WINDOWS\\SYSTEM.INI");

BOOL bResult = finder.FindFile(szFileToFind);

if (bResult)
{
finder.FindNextFile();

cout << "Root of " << szFileToFind;
cout << " is " << (LPCTSTR) finder.GetRoot();
cout << endl;

cout << "Title of " << szFileToFind;
cout << " is " << (LPCTSTR) finder.GetFileTitle();
cout << endl;

cout << "Path of " << szFileToFind;
cout << " is " << (LPCTSTR) finder.GetFilePath();
cout << endl;

cout << "URL of " << szFileToFind;
cout << " is " << (LPCTSTR) finder.GetFileURL();
cout << endl;

cout << "Name of " << szFileToFind;
cout << " is " << (LPCTSTR) finder.GetFileName();
cout << endl;

finder.Close();
}
else
cout << "You have no " << szFileToFind << " file." << endl;
