SAM_START(3)					    Corosync Cluster Engine Programmer's Manual 				      SAM_START(3)

NAME

       sam_start - Start health checking

SYNOPSIS

       #include <corosync/sam.h>

       cs_error_t sam_start (void);

DESCRIPTION

       The  sam_start  function  is  used  to start health checking of application.  After calling this function, the active process needs to send
       healthchecks within the registered time interval by calling sam_hc_send(3).  If	event  driven  healthchecking  is  configured  by  calling
       sam_register(3), an internal thread will be created and send health check confirmations four times per time_interval.

       Application must be registered by calling sam_register(3) before this function can be called.

       An application can always stop health checking by calling the sam_stop(3) function.

       If  SAM	is  initialized  with  quorum  policy  SAM_RECOVERY_POLICY_QUIT or SAM_RECOVERY_POLICY_RESTART sam_start will block until corosync
       becomes quorate.

RETURN VALUE

       This call return CS_OK value if successful, otherwise and error is returned. If SAM is initialized with quorum policy, returned	error  can
       also be quorum error.

ERRORS

       CS_ERR_BAD_HANDLE
	      component was not registered by calling sam_register(3) function.
