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
