struct

fj8283888 · #1 15-Apr-2004, 06:43

CPP / C++ / C Code:

typedef struct iorb {
    
        short base_pri;
        struct iorb *link;
        char filler[110];
        
        } IORB;

just want to know what is the difference between

CPP / C++ / C Code:

IORB *a,*b;  and
struct iorb *a,*b;

Thanks,
Frenk

Hi Frenk.

Absolutely nothing to the compiler, less typing for the user on the first one. I can't remember for sure but I think typedef is a compiler directive so this gets replaced prior to compilation, just like a #define. Anyone know for sure?

not sure, that typedef thing is c method in c++ you jus do this:

CPP / C++ / C Code:


struct iorb
{
   int a;
   int b;
   float a;
};

iorb *a , b;

p.s. i've never seen anyone using keyword struct while declaring a datatype of a structure.
