bool b_supervisor_switch_to_maintenance_mode ( void )

The switch-to-maintenance-mode command: initiate the process to
switch to maintenance mode.

References e_supervisor_switch_to_maintenance_mode(), NULL, pdTRUE, and SYS_MODID_NONE.

eExecStatus e_supervisor_switch_to_maintenance_mode	(	eModId	xModId,
		signed short	FsNavId,
		int	ac,
		signed portCHAR *	av[],
		signed portCHAR **	ppcStringReply
	)

The switch-to-maintenance-mode command: initiate the process to
switch to maintenance mode. Format: maintain.

Note: This function must be of the type pfShellCmd defined by the shell module.

Parameters

xModId	Input. The module that is calling this function.
FsNavId	Ignored.
ac	Ignored.
av	Ignored.
ppcStringReply	Input/Output. The response string. If Input is NULL, no response string will be output. Else a malloc for the response string is performed here; the caller must free this string.

Returns: the status of the command execution.
