Copy Code

There is a struct, which is a C + + Self-contained, is this:

typedef struct _win32_find_data{

DWORD dwfileattributes;// file Properties

FILETIME ftcreationtime;// File creation Time

FILETIME ftlastaccesstime;// file last access time

FILETIME ftlastwritetime;// last modified time of file

DWORD Nfilesizehigh;// High file length + bit

DWORD nfilesizelow;// Low file length + bit

DWORD dwReserved0;// System Retention

DWORD dwReserved1;// System Retention

TCHAR cfilename[MAX_PATH];// Long File name

TCHAR calternatefilename[];// Optional name of the file

} win32_find_data;
