Function CheckInvalidIncrement

src/tests/coding/cpplint.py:2660–2679

Checks for invalid increment *count++. For example following function: void increment_counter(int* count) { *count++; } is invalid, because it effectively does count++, moving pointer, and should be replaced with ++*count, (*count)++ or *count += 1. Args: filename: The name of

(filename, clean_lines, linenum, error)
