If a version of the file exists, a new file created with fopen
    inherits certain attributes from the existing file unless
    those attributes are specified in the fopen call. The following
    attributes are inherited:

       Record format
       Maximum record size
       Carriage control
       File protection

    If you specify a directory in the filename and it is a search
    list that contains an error, VSI C for OpenVMS Systems
    interprets it as a file open error.

    The file control block can be freed with the fclose function, or
    by default on normal program termination.
