  1. The return value from this function should ALWAYS be tested against 0:

  1. languagecpp
    rtn = fs_ferror(p_file);
...
  1. 
if (rtn == 0)
...
  1.  {
    // Error indicator is NOT
...
  1.  set
} else {
    // Error indicator is     set
}

  2. If the error indicator is set (i.e., fs_ferror() returns a non-zero value), fs_clearerr() can be used to clear that indicator.
