ras_path_control Exported Kernel Services

Purpose

Controls component RAS characteristics.

Syntax

#include <sys/ras.h>

kerrno_t ras_path_control ( char * path, ras_cmd_t command, void * arg, long argsize);

Description

The ras_path_control kernel service passes a command to the RAS component specified by the path parameter.

Note: During the ras_path_control process, callbacks to the registrant of the component might be initiated for changes that the RAS infrastructure makes to the component. The registrant should be aware of this for locking purposes (for instance, the registrant should not be holding any locks the callback needs).

Parameters

Item	Description
path	The pathname of the component to receive the command parameter.
command	Command passed to the callback. Commands are specific to a given RAS domain, such as Component Trace.
arg	Optional argument for the command.
argsize	Size of the argument, if a buffer or structure.

Execution Environment

The calling environment of the ras_path_control kernel service varies by individual command. The calling environment of a particular command is documented with the command itself.

Return Values

Item	Description
0	Successful.
non-zero	Unsuccessful.
