C++ function that checks for the existence of a file or directory

This article illustrates the C++ function code to check whether a file or directory exists. The specific implementation method is as follows:

#include <Windows.h>

BOOL FileExists(LPCTSTR lpszFileName, BOOL bIsDirCheck)
{
 //An attempt was made to get the file properties
 DWORD dwAttributes = ::GetFileAttributesA(lpszFileName);
 if ( INVALID_FILE_ATTRIBUTES == dwAttributes)
 {
 return FALSE;
 }

 //Is a directory
 if (dwAttributes & FILE_ATTRIBUTE_DIRECTORY)
 {
 if (bIsDirCheck) // Currently detected as well Is a directory
 {
  return TRUE;
 }
 else 
  return FALSE;
 }
 else //Is the file
 {
 if (bIsDirCheck)
 {
  return FALSE;
 }
 else 
  return TRUE;
 }
}

int main(int argc, char *argv[])
{
 BOOL bRetDir, bRetFile;
 //Test, a directory
 bRetDir = FileExists("C:\11\", TRUE);
 //Test, a file
 bRetFile = FileExists("C:\11\1.xls", FALSE); 
 return 0;
}

Hope that the article described in the C++ programming to help you.
