Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

▀ The function fails if:
  - any element of the pathname does not exist.
  - the file is being created in the root directory and the root directory
    is full.
  - the file is being created and a file with the same name and the read-
    only attribute already exists in the specified directory.
  - the program is running on a network and the user running the program
    has insufficient access rights.
 
▀ A file is usually given a normal (0) attribute when it is created.
 
▀ The file's attribute can subsequently be modified with Int 21H Function
  43H. This function combines the capabilities of Int 21H Functions 3CH,
  3DH, and 5BH. It was added to MS-DOS for compatibility with the DosOpen
  function of OS/2.
