Macros
#define	SMF_CREATE_STATE(_entry, _run, _exit, _parent, _initial)
	Macro to create a hierarchical state with initial transitions.
#define	SMF_CTX(o)   ((struct smf_ctx *)o)
	Macro to cast user defined object to state machine context.

Typedefs
typedef void(*	state_execution) (void *obj)
	Function pointer that implements a portion of a state.

Functions
void	smf_set_initial (struct smf_ctx *ctx, const struct smf_state *init_state)
	Initializes the state machine and sets its initial state.
void	smf_set_state (struct smf_ctx *ctx, const struct smf_state *new_state)

void	smf_set_terminate (struct smf_ctx *ctx, int32_t val)
	Terminate a state machine.
void	smf_set_handled (struct smf_ctx *ctx)
	Tell the SMF to stop propagating the event to ancestors.
int32_t	smf_run_state (struct smf_ctx *ctx)
	Runs one iteration of a state machine (including any parent states)
