LSMD(1) 						   libStorageMgmt plug-in daemon						   LSMD(1)

NAME
Daemon - lsmd DESCRIPTION
libStorageMgmt plug-in daemon. Plug-ins execute in their own process space for fault isolation and to accommodate different plug-in licensing requirements. Runs as an unprivileged user. OPTIONS
--plugindir = The directory where the plugins are located --socketdir = The directory for IPC sockets -v = Verbose logging -d = New style daemon (systemd) non-forking BUGS
Please report bugs to <libstoragemgmt-devel@lists.sourceforge.net> AUTHOR

NAME
picld_plugin_register - register plug-in with the daemon SYNOPSIS
cc [ flag... ] file... -lpicltree [ library... ] #include <picltree.h> int picld_plugin_register(picld_plugin_reg_t *regp); DESCRIPTION
The picld_plugin_register() function is the function used by a plug-in module to register itself with the PICL daemon upon initialization. The plug-in provides its name and the entry points of the initialization and cleanup routines in the regp argument. typedef struct { int version; /* PICLD_PLUGIN_VERSION */ int critical; /* is plug-in critical? */ char *name; /* name of the plugin module */ void (*plugin_init)(void); /* init/reinit function */ void (*plugin_fini)(void); /* fini/cleanup function */ } picld_plugin_reg_t; The plug-in module also specifies whether it is a critical module for the proper system operation. The critical field in the registration information is set to PICLD_PLUGIN_NON_CRITICAL by plug-in modules that are not critical to system operation, and is set to PICLD_PLUG- IN_CRITICAL by plug-in modules that are critical to the system operation. An environment control plug-in module is an example for a PICLD_PLUGIN_CRITICAL type of plug-in module. The PICL daemon saves the information passed during registration in regp in the order in which the plug-ins registered. Upon initialization, the PICL daemon invokes the plugin_init() routine of each of the registered plug-in modules in the order in which they registered. In their plugin_init() routines, the plug-in modules collect the platform configuration data and add it to the PICL tree using PICLTREE interfaces(3PICLTREE). On reinitialization, the PICL daemon invokes the plugin_fini() routines of the registered plug-in modules in the reverse order of registra- tion. Then, the plugin_init() entry points are invoked again in the order in which the plug-ins registered. RETURN VALUES
Upon successful completion, 0 is returned. On failure, a negative value is returned. ERRORS
PICL_NOTSUPPORTED Version not supported PICL_FAILURE General system failure ATTRIBUTES
