Gets long or short options, specified in options[] (see docs/dev/longopt.dev).Call it iteratively with the same info_buf until it returns 0 or -1.0 means you have reached the end of options.-1 means a parse error, with error put in info_buf->opt_error.Any other value is a valid option identifier.
static int longopt_get_longopt
Find the option identifier of a long option.Fill info_buf appropriately, and return the option identifier.argv[info_buf-opt_index]> is guaranteed to have at least three characters and start with --.
static int longopt_get_shortopt
Find the option identifier of the next short option.This next short option may be in the middle of a bundle (-abcd), and info_buf->_shortopt_pos maintains a pointer into that bundle.argv[info_buf->opt_index] is guaranteed to be at least two characters long and start with a dash.
