My preference is for separate lines, and "if (NULL == x)"

Reasoning:

  1) separate lines allow you to see the result of the call in a
  debugger. You can't when you use functions inside if statements. 

  2) putting the constant on the left, as with the (NULL == x),
  catches the case where you use an = instead of a ==, so I think it
  is less error prone.
