[PATCH] D56136: [compiler-rt] [sanitizer_common] Add tests for more stdio.h functions

[Vitaly Buka via Phabricator via cfe-commits]

vitalybuka added inline comments.


================
Comment at: test/sanitizer_common/TestCases/Posix/feof_fileno_ferror.cc:49
+
+  fclose(fp);
+  return 0;
----------------
why does this close file only on success?
I assume normal test behavior is return 0;
So please replace all return N with  asserts so when it fail we will have verbose output
e.g
```
assert(close(fd) != -1);
....
assert(ferror(fp));
```
