recursive search

I am doing a recursive searching the "C:\" drive on a Windows PC with FindFirstFile and FindNextFile. I am not the administrator and the program stops when I hit a directory that when I do a ls -l from the command prompt shows the directory as "Permission denied". How can the program determine if it doesn't have permission to access a directory? Thanks

Can you post the code you're using?

EDIT: Maybe GetFileAttributes() would work, but I'm not really sure.

The FindFirstFile / FindNextFile APIs fill a WIN32_FIND_DATA structure pointed by lpFindFileData ). The dwFileAttributes data member of this struct contains the attributes needed by you:

Code:

typedef struct _WIN32_FIND_DATA {
  DWORD    dwFileAttributes; 
  FILETIME ftCreationTime; 
  FILETIME ftLastAccessTime; 
  FILETIME ftLastWriteTime; 
  DWORD    nFileSizeHigh; 
  DWORD    nFileSizeLow; 
  DWORD    dwReserved0; 
  DWORD    dwReserved1; 
  TCHAR    cFileName[ MAX_PATH ]; 
  TCHAR    cAlternateFileName[ 14 ]; 
} WIN32_FIND_DATA, *PWIN32_FIND_DATA;

On the other hand, you should check the return values of FindFirstFile / FindNextFile, in case of failure evaluate the error given by GetLastError().
