[Frama-c-discuss] fopen and null pointers

  • Subject: [Frama-c-discuss] fopen and null pointers

When I'm using "fopen" in a test case and comparing it's result
with NULL I get a warning in the value analysis:

  fp = fopen("./seq","r");
  /*@ assert Value: ptr_comparison: \pointer_comparable(fp, (void *)0); */

Is there a way I can annotate this call or the fopen function
to specify that NULL is a valid return value?
