HELPLIB.HLB  —  CRTL  decc$translate_vms
    Translates OpenVMS file specifications to UNIX style file
    specifications.

    Format

      #include  <unixlib.h>

      char *decc$translate_vms  (const char *vms_filespec);

1  –  Argument

 vms_filespec

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

2  –  Description

    The decc$translate_vms function translates the given OpenVMS file
    specification into the equivalent UNIX style file specification,
    whether or not the file exists. The translated name string is
    stored in a thread-specific memory, which is overwritten by each
    call to decc$translate_vms from the same thread.

    This function differs from the decc$from_vms function, which does
    the conversion for existing files only.

3  –  Return Values

    x                  The address of a null-terminated string
                       containing a name in UNIX style file
                       specification format.
    0                  Indicates that the filename is null or
                       syntactically incorrect.
    -1                 Indicates that the file specification contains
                       an ellipsis (for example, [ . . . ]a.dat), but
                       is otherwise correct. You cannot translate
                       the OpenVMS ellipsis syntax into a valid UNIX
                       style file specification.

        /* Demonstrate translation of a "UNIX" name to OpenVMS  */
        /* form, define a foreign command, and pass the name as */
        /* the argument.                                        */

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

        int main(int argc, char *argv[])
        {
            char *ptr;                      /* translation result */

            ptr = decc$translate_vms( argv[1] );

            if ((int) ptr == 0 || (int) ptr == -1)

                printf( "could not translate %s\n", argv[1]);
            else
                printf( "%s is translated to %s\n", argv[1], ptr );
        }
