      D_SETFILES

SUMMARY
   d_setfiles(num)
   int num;

ARGUMENTS

   num       The maximum number of open files.

DESCRIPTION
   This function sets the maximum number of files that the db_VISTA runtime
   can have open at one time. Both MS-DOS and UNIX limit the number of files
   that an application program can have open. The default limit for MS-DOS
   is 8 (but is configurable up to 20, possibly more on certain network).
   The limit of UNIX is 20. Thus, if a program opens 6 files and the operating
   system limit is 20, the most num can be is 14 (i.e. the db_VISTA runtime
   can heve 14 of its own files open at time).

   Function d_setfiles should be called before d_open. The default value is
   initially set to 5.

--------------------------------------------------------------------------
Note:
   If num is set too high, then once the operating system limit has been
   reached and db_vista attempts to open another file, error code S_NOFILE
   may be returned by any db_VISTA function which accesses information in the
   database.
