typedef struct vs struct definitions [duplicate]

Answer 1

Another difference not pointed out is that giving the struct a name (i.e. struct myStruct) also enables you to provide forward declarations of the struct. So in some other file, you could write:

struct myStruct;
void doit(struct myStruct *ptr);

without having to have access to the definition. What I recommend is you combine your two examples:

typedef struct myStruct{
    int one;
    int two;
} myStruct;

This gives you the convenience of the more concise typedef name but still allows you to use the full struct name if you need.
