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? -- Tim Newsham | www.thenewsh.com/~newsham | @newshtwit | thenewsh.blogspot.com -------------- next part -------------- An HTML attachment was scrubbed...
