Question
Dear sir
Could you plese tell me what is the static function in C programming? where it is used? & what is their pecularity(if any) ?  

Answer
static is a qualifier in C.
It tells that whatever is declared with static will have a local scope and will live till the program exits.
For any function in C program, its scope is global.
So, if your program spans more than one file, then you can access functions in different files.
If you put static infront of a function, it becomes local to a file. That means another function residing in another file (ofcourse it also belongs to the same program) cannot access this funtion.

Hope it is clear now.
