Converts OpenVMS file specifications to UNIX style file
    specifications.

    Format

      #include  <unixlib.h>

      int decc$from_vms  (const char *vms_filespec, int
                         action_routine, int wild_flag);

1 - Arguments

 vms_filespec

    The address of a null-terminated string containing a name in
    OpenVMS file specification format.

 action_routine

    The address of a routine that takes as its only argument a null-
    terminated string containing the translation of the given OpenVMS
    filename to a valid UNIX style filename.

    If the action_routine returns a nonzero value (TRUE), file
    translation continues. If it returns a zero value (FALSE), no
    further file translation takes place.

 wild_flag

    Either 0 or 1, passed by value. If a 0 is specified, wildcards
    found in vms_filespec are not expanded. Otherwise, wildcards
    are expanded and each one is passed to action_routine. Only
    expanded filenames that correspond to existing UNIX style files
    are included.

2 - Description

    The decc$from_vms routine converts the given OpenVMS file
    specification into the equivalent UNIX style file specification.
    It allows you to specify OpenVMS wildcards, which are translated
    into a list of corresponding existing files in UNIX style file
    specification format.

3 - Return Value

    x                  The number of filenames that result from the
                       specified OpenVMS file specification.

4 - Example

        /* This example must be run as a foreign command        */
        /* and be supplied with an OpenVMS file specification.  */

        #include <unixlib.h>
        #include <stdio.h>

        int main(int argc, char *argv[])
        {
            int number_found;           /* number of files found */
            int print_name();           /* name printer          */

            printf("Translating: %s\n", argv[1]);
            number_found = decc$from_vms(argv[1], print_name, 1);
            printf("\n%d files found", number_found);
        }

        /* print the name on each line */
        print_name(char *name)
        {
            printf("\n%s", name);
            /* will continue as long as success status is returned */
            return (1);
        }

      This example shows how to use the decc$from_vms routine in
      Compaq C. It produces a simple form of the ls command that
      lists existing files that match an OpenVMS file specification
      supplied on the command line. The matching files are displayed
      in UNIX style file specification format.
