void fun(char **) - What is this function all about?

That's not enough information. Anyone can write a function named "fun" that takes a "char **" argument.

Did you see a function in some source code somewhere that you're asking about? If you did, post the function, or post a link to it so we can look at it and comment.

ganz6513void fun(char **) what is this function all about??? P.S im a beginner😁

Post the whole function mate, how could anyone guess, what is meant for without looking at the code?

If possible put the whole program here.

Always ask your questions with maximum details you can provide, it would help you to get your query solved at the earliest.

PS: char ** means pointer to a pointer which can store address of char type variable..

Note that the function Fun will have return type Void and it will take a value Which has to be of pointer to pointer type of Data type Character
