175   The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
176   of 'struct option' terminated by an element containing a name which is
177   zero.
178
179   The field 'has_arg' is:
180   no_argument          (or 0) if the option does not take an argument,
181   required_argument    (or 1) if the option requires an argument,
182   optional_argument    (or 2) if the option takes an optional argument.
183
184   If the field 'flag' is not NULL, it points to a variable that is set
185   to the value given in the field 'val' when the option is found, but
186   left unchanged if the option is not found.
187
188   To have a long-named option do something other than set an 'int' to
189   a compiled-in constant, such as set a value from 'optarg', set the
190   option's 'flag' field to zero and its 'val' field to a nonzero
191   value (the equivalent single-letter option character, if there is
192   one).  For long options that have a zero 'flag' field, 'getopt'
193   returns the contents of the 'val' field.  */

220   Return the option character from OPTS just read.  Return -1 when
221   there are no more options.  For unrecognized options, or options
222   missing arguments, 'optopt' is set to the option letter, and '?' is
223   returned.
224
225   The OPTS string is a list of characters which are recognized option
226   letters, optionally followed by colons, specifying that that letter
227   takes an argument, to be placed in 'optarg'.
228
229   If a letter in OPTS is followed by two colons, its argument is
230   optional.  This behavior is specific to the GNU 'getopt'.
231
232   The argument '--' causes premature termination of argument
233   scanning, explicitly telling 'getopt' that there are no more
234   options.
235
236   If OPTS begins with '-', then non-option arguments are treated as
237   arguments to the option '\1'.  This behavior is specific to the GNU
238   'getopt'.  If OPTS begins with '+', or POSIXLY_CORRECT is set in
239   the environment, then do not permute arguments.  */
