int odb_update_node	(	odb_t *	odb,

		unsigned long int	offset
	)

odb_update_node_with_offset

Parameters:

	odb	the data base object to setup
	key	the hash key
	offset	the offset to be added

update info at key by adding the specified offset to its associated value, if the key does not exist a new node is created and the value associated is set to offset.

returns EXIT_SUCCESS on success, EXIT_FAILURE on failure
