The attached program experiments with getopt_long. It prints optarg for each option, or (null) if optarg is NULL. If I attempt to use the -o option I get the following results. $ ./getopt_test -o optional argument: (null) $ ./getopt_test -o arg optional argument: (null) Non - option ARGV elements: arg This happens for me with glibc 2.1.2 on x86 and ARM. The -o option is supposed to take an optional argument. The documentation leads me to believe that optarg will be set if an argument for the option exists. Have I missed something or is this a bug?
