SAM_D...STORE(3) Corosync Cluster Engine Programmer's Manual SAM_D...STORE(3) NAME sam_data_restore - Restore previously saved user data SYNOPSIS #include <corosync/sam.h> cs_error_t sam_data_restore (void *data, size_t size); DESCRIPTION The sam_data_restore function is used to restore data, previously saved by calling sam_data_store(3). Such data survives between instances. The data parameter is pointer to memory initialized by caller. Stored data are copied there. This also means, that caller is responsible for freeing memory. The size parameter is length of data. This one must be at least same length as previously stored data otherwise error is returned. Parameter can be larger but only stored data size bytes are changed. Use sam_data_getsize(3) to find out length of stored data. RETURN VALUE This call return CS_OK value if successful, otherwise and error is re- turned. ERRORS CS_ERR_BAD_HANDLE component was not initialized by calling sam_initialize(3) or it was finalized. CS_ERR_INVALID_PARAM data parameter is NULL or size is less then currently stored data length SEE ALSO sam_data_getsize(3), sam_data_store(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 interrupted by a signal CS_ERR_NOT_SUPPORTED The requested protocol/functionality not supported CS_ERR_MESSAGE_ERROR Incorrect auth message received CS_ERR_NO_MEMORY Not enough memory to complete the requested task corosync Man Page 04/15/2010 SAM_D...STORE(3)
