The return value of remove() is deliberately not checked because it is expected to fail if the file does not exist. If the file exists but cannot be removed, the rename() call will also fail, and the error will be detected at that point. This is a valid exception (EXP12-C-EX1) to EXP12-C. Do not ignore values returned by functions.
