c99 - bizarre C statement -

this question has answer here:

• what purpose of static keyword in array parameter of function “char s[static 10]”? 1 answer

void test(int x[static 10]);    int main()   {       int a[]={1,2,3,4,5,6,7,8,9,10,11};       test(a);       return 0;   }    void test(int x[static 10])   {       printf("%d",x[9]);   }  

i looking bizarre c statements. found one, not understand use of static 10 in statement. same int x[10]?

another thing, can use volatile also, in place of static e.g int x[volatile 10]
knows use of kinda declaration?

ps: compiled using gcc 4.6.3,

it's hint compiler telling x pointer parameter points first element of array of @ least 10 elements.

for example:

test(null);  // undefined behavior
