Question

If I have the following:

typedef struct _MY_STRUCT
{
   int a;
   float b;
} MY_STRUCT, *PMYSTRUCT

What does *PMYSTRUCT do? Is it now a pointer type which I need to declare or just a pointer to _MY_STRUCT which I can use?

I know that MY_STRUCT is a new type that needs to be used as follows:

MY_STRUCT str;
str.a = 2;

But what about that *PMYSTRUCT?

Answer 1

PMYSTRUCT ms = NULL;

is equal to

MYSTRUCT* ms = NULL;
