But isn't it incorrect? POSIX 2018 says:'"\ddd", where ddd is a one, two, or three-digit octal number, shall be written as a byte with the numeric value specified by the octal number.' since 477 -> 777 are not byte values, shouldn't \777 be interpreted as '\77' octal then the digit 7; \677 -> \67 octal then 7 etc. ?
Better to do what the C compiler does: try converting up to 3 digits, and if the result of the conversion is > 255, complain. -RVP
