带有FIFO的结构

Question

I'm having some trouble with structs..

I have the following code:

typedef struct filaNo{   
     Range data;   
     struct filaNo* prox; 
  }tfilaNo;                    

typedef struct tfifo {        
     tfilaNo* inicio;   
     tfilaNo* final;       
  } tfifo;  

And I want to include this list in another struct:

typedef struct  
{
int    threadId;
    double threshold;
    double areaCalc;
    tfifo  intervalos;
}ThreadData;

When I use only tfifo it works perfectly, but when I include into ThreadData I receive 55 errors (like: "syntax error: identifier 'tfifo'"...) and so many others like this... seems like the compiler is lost.

Does anyone know how to solve this?

Thank you very much!

EDIT: some more code :)

tfifo works fine alone, I can do something like this:

tfila doc;                                     
Range range;
int a;   

create_fifo(&doc);      

range.p1.x = 0;
range.p2.x = 33;
range.p1.y = 0;
range.p2.y = 0;
range.area = 0;

insert_fifo (&doc, range);   

while(!empty_fifo(doc)){   
    remove_fifo(&doc,&range);         
    printf("    %d\n", range.p2.x);   
}        

Now I want to include this into ThreadData, because I need a list for every ThreadData struct.

Error 2 error C2059: syntax error : '}' Error 1 error C2061: syntax error : identifier 'tfila'
Error 18 error C2065: 'i' : undeclared identifier

But the compiler gets totally lost after this... giving me so many errors that doesn't exist...

Answer 1

Is this the real code or a typo?

typedef struct tfifo {        
 tfilaNo* inicio;   
 tfilaNo* final;       

} tfifo;

You are using the same name for the struct and the typedef. Maybe this is the problem.

Answer 2

In C , you need Use like this

typedef struct struct_name
{
//...
}mytype_t;

Modify this

typedef struct give_some_name  
{
int    threadId;
    double threshold;
    double areaCalc;
    tfifo  intervalos;
}ThreadData;  

EDIT

Here you are using same name modify this also

typedef struct tfifo_t {        
     tfilaNo* inicio;   
     tfilaNo* final;       
  } tfifo;
