How to typedef

I want to declare
char ch[9] as ch_9 with the help of the typedef statement.

Thanks

How about

typedef char ch_9[9];

however you can't do this...

ch_9 my_func(int x)
{
  ch_9 blah;

  return blah;
}

As in specific cases arrays are treated as pointers.

In that case you would have to do

typedef struct { char ch[9]; } ch_9;
