passing 2-Dimensional Array to a function

greetings C gurus,

I would be grateful if I could know the answers to 2 questions:

1. I want to know how to pass a 2-dimensional array to a function, say
foo() and what will be its prototype declaration?
2. Is there any difference between the name of a 2-dimensional char
array and a 'pointer-to-a pointer-to-a-char' in other words, is the
following true?

char array[5][10], **ptr ;
ptr = array ;
actual examples of code or links to code using 2-dimensional arrays
passed to functions will be highly appreciated.
thanks in advance...
yours sicerely,
seemanta dutta ;-)

Recommended reading: Section 6 "Arrays and Pointers"
in the comp.lang.c Frequently Asked Questions (FAQ) list

http://www.eskimo.com/~scs/C-faq/top.html

The explanations therein are terse, but perhaps the
clearest I've come across.
