[PATCH v2 2/2] dtc: ensure that command line options arrays length match

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

usage_long_opts and usage_opts_help should always have the same length.
Since these are fixed length arrays, this can be checked at compile time
with _Static_assert (requires C11).
