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

NAME

       sam_mark_failed - Mark process failed

SYNOPSIS

       #include <corosync/sam.h>

       cs_error_t sam_mark_failed (void);

DESCRIPTION

       The sam_mark_failed function is used with SAM_RECOVERY_POLICY_CMAP mostly together with SAM_RECOVERY_POLICY_RESTART to mark process failed.
       Process marked failed is killed without sending warn signal and control process will exit as with  SAM_RECOVERY_POLICY_QUIT  policy.  Condb
       key state will be set to failed so corosync watchdog can take required action.

RETURN VALUE

       This call return CS_OK value if successful, otherwise and error is returned.

ERRORS

       CS_ERR_BAD_HANDLE
	      library was not initialized by calling sam_initialize(3) or was already finalized

       CS_ERR_INVALID_PARAM
	      recovery policy doesn't has SAM_RECOVERY_POLICY_CMAP flag set

       CS_ERR_LIBRARY
	      some internal error appeared (communication with parent process)

SEE ALSO

       sam_initialize(3)

       CS_ERR_TRY_AGAIN Resource temporarily unavailable

       CS_ERR_INVALID_PARAM Invalid argument

       CS_ERR_ACCESS Permission denied

       CS_ERR_LIBRARY The connection failed

       CS_ERR_INTERRUPT System call inturrupted by a signal

       CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported

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

NAME

       sam_data_store - Store user data

SYNOPSIS

       #include <corosync/sam.h>

       cs_error_t sam_data_store (const void *data, size_t size);

DESCRIPTION

       The sam_data_store function is used to store data, which survives between instances.

       The  data parameter is pointer to memory with data to store. Data are stored in newly allocated memory inside library, so caller can safely
       remove them after call of function.

       You can use NULL as parameter to remove and free previously saved data. In this case size argument is ignored.

       The size parameter is length of data.

       Use sam_data_getsize(3) to find out length of stored data and sam_data_restore(3) to restore stored data.

RETURN VALUE

       This call return CS_OK value if successful, otherwise and error is returned.

ERRORS

       CS_ERR_BAD_HANDLE
	      component was not initialized by calling sam_initialize(3) or it was finalized.

       CS_ERR_NO_MEMORY
	      internal	malloc/realloc failed because data are too large

       CS_ERR_LIBRARY
	      some internal error appeared (mostly because communication with parent process failed)
