Thread: Restricted pointers C99.

Hello to all according to the theory this snippet of code :

Code:

#include<stdio.h>
void f( int * restrict p , int *q);

int main( void )
{
	int x=3;
	
	f(&x , &x);
	
	printf("%d" , x);
	
return 0;
}
void f ( int * restrict p , int *q ) 
{
	(*q) += 1;  // x = 4
	
	*q = *p + 2;  // x = 6
	
	return;
}

procudes Undefined Behaviour or not? I think yes... but I am not sure.

Thank you in advance for your time.
