what is a static function in C ?

[sbmoon]

Is there any difference between two functions defined below ?

static int my_func() ;

int my_func() ;

Thanks in advance!

Your friendly C textbook should have already explained this.
A static function has a name visible in that translation unit only. A
normal function has a name visible across the entire program.
If you were to have two source files:
static int foo() {
return 0;
}
int bar() {
return 0;
}
(both files look the same)
you would get "function already defined" errors for bar, but foo would
compile absolutely OK.
