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
