C gurus

what do two ** mean?
one * means pointer

but what do the two ** mean in the following?

char *strsep(char ** stringp , const char * delim );

thanks

Does it matter where the asterix goes? I thought you could put the asterix after a variable name and it would still be a pointer. Like:

*int

or

int*

and they were synonomous. That must not be the case though because if it was, that line of code wouldn't really make any sense, I don't think, because you can't have a variable named "char." Well, I'm confused.

it means a pointer to a pointer

in the case of char ** it usually means an array of strings


do you understand why?

 

[johnjbruin]

yeah
i figured it out

thanks ameesh, i had to change the way of referencing/dereferencing it

C gurus? Is this for a class or something? I've not seen a book on C w/o including pointers to pointers. I want a free online book about preprocessor jazz though...anyone have links?

 

[Ameesh]

i learned all my preprocesser stuff from example, i would also like to find a nice wuick refrence about it.

A nice quick reference?

K&R is perhaps the only C language book you'll ever need.

Do you guys think sitting with a book and C++ in front of me that I can learn it from scratch? Is it viable?

it doesnt have a lot of preprocesser stuff in it
