This warning indicates that a variable holding a sizeof result is being added to or subtracted from a pointer or countof expression. This will cause unexpected scaling in pointer arithmetic.

The following code generates this warning:

void f(int *p)   
{   
  int cb=sizeof(int);   
  //code...   
  p +=cb; // warning 6305  
}  

To correct this warning, use the following code:

void f(int *p)   
{  
  // code...  
  p += 1;   
}
