pointers names with one and two asterisks?

hubabuba · 03-19-2006, 03:34 PM

Hi All!

I saw pointers with one and two asterisks, like this:

*pointer_name
**pointer_name

Can anyone tell me what do the two asterisks stand for?
I tried looking up, but didn't find anything useful.

Thanks

One asterisk is for a pointer as you seem to know and then, following the pattern here, two asterisks mean it's a pointer to a pointer ofcourse

You need to look at how they are defined. However one possible solution would be that the second is an array of pointers, and so the first asterisk dereferences to the first element in the array, whilst the second will dereference to the actual data pointed at by the first element.

If that was the case the following would be identical

Code:

*pointer[0]
**pointer
