CfgMgr::CancelMonitor

**Table 1** Description of CfgMgr::CancelMonitor
Prototype	uint32_t CfgMgr::CancelMonitor(const std::string &kParam = "")
Description	Cancels listening.
Function Security Level	ASIL-D
Parameter (IN)	kParam	Key value, for example, use_sim_time. By default, this parameter is left blank, indicating that listening on all parameters is canceled.
Parameter (OUT)	None
Return	uint32_t	CFGMGR_SUCCESS is returned upon success; otherwise, the corresponding error code is returned.
Usage	None
Precautions	If the callback function registered by the Monitor is being executed when the listening is canceled, the function is deregistered after the callback is processed. If kParam is listened for multiple times (see CfgMgr::Monitor), all functions are deregistered when listening is canceled. If CfgMgr::Monitor is called,CancelMonitor must be called to destroy threads when processes exit. Otherwise, a core dump may occur. If OpenHiva::Shutdown is called, CancelMonitor does not need to be called because OpenHiva::Shutdown calls CancelMonitor by default.
