cfg_subsys_config(3) Library Functions Manual cfg_subsys_config(3)
NAME
cfg_subsys_config - Configure a subsystem
LIBRARY
Configuration Management Library (libcfg.a)
SYNOPSIS
#include <cfg.h> cfg_status_t cfg_subsys_config(
cfg_handle_t *handle,
caddr_t subsys);
PARAMETERS
Structure identifying the means of communication between your application and the configuration management server. For local requests,
pass NULL in this parameter. For remote requests, pass the value returned from the cfg_connect routine. Names the subsystem to be config-
ured.
DESCRIPTION
To initially configure a subsystem into the kernel, call the cfg_subsys_config() routine. If the subsystem is not loaded into the kernel,
this routine loads the subsystem. The routine then configures the subsystem using the attribute settings from the /etc/sysconfigtab data-
base. If no attributes are set in the database, the default values defined in the subsystem code are used.
Each subsystem is contained in a module file named subsystem-name.mod. For example, a subsystem named mysubsystem is contained in the
mysubsystem.mod module file. This module file must exist in the /subsys, /var/subsys, or /sys/BINARY directory on the system you are con-
figuring.
EXAMPLES
The following example illustrates the use of the cfg_subsys_config() routine:
cfg_status_t retval; cfg_handle_t handle;
retval = cfg_subsys_config(&handle, "vfs");
if (retval != CFG_SUCCESS)
print_error(retval);
In this example, the cfg_subsys_config() routine attempts to configure the vfs subsystem. If an error is returned, the corresponding error
message is displayed to the application user.
RETURN VALUES
Upon successful completion, cfg_subsys_config() returns CFG_SUCCESS. Other return values indicate that an error has occurred. For infor-
mation about handling return values from routines in the configuration management library, see libcfg(3).
