Let us make it clear

int x=22;//global

int* function()
{
static int x = 99; // static x in function
return &x;
}

main()
{
{
//static x in block
static int x = 88;

//returns static in block
printf("\nvalue: %d", x++);

// static x in function
int *p = function();
printf("\nvalue from function: %d", *p);

// change static x in function
*p = 77;

printf("\nvalue from function: %d", *p);
// new value of static x declared in function
}
// returns global x
printf("\nvalue: %d", x);

//still static x declared in function is alive in memory
//but cannot be accessed directly as X since the scope of
//x declared in function is limited to the boundary of
//the function
printf("\nvalue from function: %d", *function());
}
