class_save_database(3)
NAME
  class_save_database - Write the in-memory database to disk.

LIBRARY
  Standard C Library (libclass.a)

SYNOPSIS
  #include <apar_types.h>
  #include <sys/class.h>

  class_save_database (class_apar_handle_t handle,
  dbase_name);

PARAMETERS
  handle
      The partition descriptor returned by class_open().

  dbase_name
      An optional file name in which the database will be saved.

DESCRIPTION
  The class scheduler database is memory shared by the administration
  command, the class scheduler daemon, and runclass(). Administrative changes
  (such as adding a gid to a class) need to be saved to disk so that the
  changes are available at the next reboot. Note that class scheduler
  administrative changes take effect immediately whether they are written to
  disk or not.

  If the dbase_name argument is supplied, the database will be written to the
  specified file name. The current database name will be used by default if
  dbase_name is null.

  Note that the calling process must have root access privileges.

RETURN VALUES
  [CLASS_SUCCESS]
      The operation successfully completed.

  [CLASS_INVAL_PARTITION]
      An invalid partition handle was specified.

  [CLASS_NAME_TOO_LONG]
      The dbase_name size limit is exceeded.

  [CLASS_FILE_FAILURE]
      Error in writing the file, indicated by ERRNO
