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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.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 path name 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.
