   D_INITFILE

SUMMARY
   d_initfile(FILEID[,dbn])
   int FILEID;
   int dbn;

ARGUMENTS
   FILEID      The file identifier constant of the databse file to be
               initialized.

   dbn         (optional)The number of the database containing the record

DESCRIPTION
   Function d_initfile can be used to initialize (or reinitialize) individual
   data and key files within a database.The FILEID is the file identifier
   constant defined in the dbname.dbd file ,generated by ddlp when the
   "fileid=filename" clause occurs in a data or key file statement in DDL.

   This function can cause database corruption if not used properly.It does
   not clean up set pointers within other files which may point to an
   initialized file.Neither will delete keys from a key file (if a data file is
   initialized) or records in a data file (if a key file is initialized).
   Care must be taken to only initialize independent groups of files.


-------------------------------------------------------------------
NOTE
   This function can only be called when databse is opened in exclusive
   or one-user-only access mode.

   In db_VISTA 3.00 for DOS enviroments ,this function did not require the
   presence of the data/or key file to function.However, for UNIX
   enviroments, it did.This has been changed with db_VISTA 3.10. The
   data and/or key files now must exist in order for this function
   to work .You will get an S_NOFILE (-905) error if any file is missing.
   This change was made db_VISTA behave the same regardless of the platform
   which it is runnig.

RETURN CODES

   -32   S_EXCLUSIVE        Function requires exclusive or one-user database
                            access.

EXAMPLE


  DDL:

    database work{
       data file work_data="work.d" contains ....
       key file work_key="work.k" contains ....

  C Code:

       char dbnames[80];
       ....
       strcpy(dbnames,"work;");  /* db 0 will be work database  */
       strcat(dbnames,userdb);   /* db 1 will be user database  */
       d_open(dbnames,"x");


       /* initialize work databse files  */

       d_initfile(WORK_DATA,0);
       d_initfile(WORK_KEY,0);
       .......
