CreateDirectoryEx

The CreateDirectoryEx function creates a new directory with the attributes of a specified template directory. If the underlying file system supports security on files and directories, the function applies a specified security descriptor to the new directory. The new directory retains the other attributes of the specified template directory.

BOOL CreateDirectoryEx(
  LPCTSTR lpTemplateDirectory,               // template directory
  LPCTSTR lpNewDirectory,                    // directory name
  LPSECURITY_ATTRIBUTES lpSecurityAttributes // SD
);

Parameters

lpTemplateDirectory

[in] Pointer to a null-terminated string that specifies the path of the directory to use as a template when creating the new directory.

Windows NT/2000: In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to nearly 32,000 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see File Name Conventions.

Windows 95/98: This string must not exceed MAX_PATH characters.

lpNewDirectory

[in] Pointer to a null-terminated string that specifies the path of the directory to be created.

Windows NT/2000: In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to nearly 32,000 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see File Name Conventions.

Windows 95/98: This string must not exceed MAX_PATH characters.

lpSecurityAttributes

Windows NT/2000: [in] Pointer to a SECURITY_ATTRIBUTES structure. The lpSecurityDescriptor member of the structure specifies a security descriptor for the new directory. If lpSecurityAttributes is NULL, the directory gets a default security descriptor. The target file system must support security on files and directories for this parameter to have an effect.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The CreateDirectoryEx function allows you to create directories that inherit stream information from other directories. This function is useful, for example, when dealing with Macintosh directories, which have a resource stream that is needed to properly identify directory contents as an attribute.

Some file systems, such as NTFS, support compression or encryption for individual files and directories. On volumes formatted for such a file system, a new directory inherits the compression and encryption attributes of its parent directory.

Windows NT/2000: You can obtain a handle to a directory by calling the CreateFile function with the FILE_FLAG_BACKUP_SEMANTICS flag set. See CreateFile for a code example.

Requirements

  Windows NT/2000: Requires Windows NT 3.5 or later.
  Windows 95/98: Requires Windows 95 or later.
  Header: Declared in Winbase.h; include Windows.h.
  Library: Use Kernel32.lib.
  Unicode: Implemented as Unicode and ANSI versions on Windows NT/2000.
