简练状态机的实现

#include<stdio.h>

typedef enum{

Start_state,

Doing_state,

End_state

}def_state;

typedef enum{

Start_event,

Doing_event,

End_event

}def_event;

typedef void (*func)(char* pData);

typedef struct{

def_state current_state;

def_event current_event;

def_state next_state;

func callback;

}def_Machine_state;

void start_task(char *pData)

{

    printf("start task!\n");

}

void doing_task(char *pData)

{

    printf("doing task!\n");

}

void end_task(char *pData)

{

    printf("end task!\n");

}

def_Machine_state Machine_run[]={

Start_state, Start_event, Doing_state, start_task,

Doing_state, Doing_event, End_event,  doing_task,

End_event, End_event, End_event,    end_task,

};

void loop_machine(def_event trigger_eve,char *pData)

{

    int size;

    size = sizeof(Machine_run)/sizeof(def_Machine_state);

    for(int i=0; i<size;i++)

    {

        if(trigger_eve == Machine_run[i].current_event)

        {

        Machine_run[i].callback(pData) ;

        }

    }

}

main()

{

char *debug;

while(1){

loop_machine(Start_event,debug);

loop_machine(Doing_event,debug);

loop_machine(End_event,debug);

}

}

该简单状态机设置了三个状态，三个事件触发。

运行结果
