81/* Standalone applications get correct prototypes for getopt_long and
82 getopt_long_only; they declare "char **argv". libc uses prototypes
83 with "char *const *argv" that are incorrect because getopt_long and
84 getopt_long_only can permute argv; this is required for backward
85 compatibility (e.g., for LSB 2.0.1).
86
87 This used to be '#if defined __GETOPT_PREFIX && !defined __need_getopt',
88 but it caused redefinition warnings if both unistd.h and getopt.h were
89 included, since unistd.h includes getopt.h having previously defined
90 __need_getopt.

92 The only place where __getopt_argv_const is used is in definitions
93 of getopt_long and getopt_long_only below, but these are visible

166 The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
167 of 'struct option' terminated by an element containing a name which is
168 zero.
169
170 The field 'has_arg' is:
171 no_argument (or 0) if the option does not take an argument,
172 required_argument (or 1) if the option requires an argument,
173 optional_argument (or 2) if the option takes an optional argument.

176 to the value given in the field 'val' when the option is found, but
177 left unchanged if the option is not found.
178
179 To have a long-named option do something other than set an 'int' to
180 a compiled-in constant, such as set a value from 'optarg', set the
181 option's 'flag' field to zero and its 'val' field to a nonzero
182 value (the equivalent single-letter option character, if there is
183 one). For long options that have a zero 'flag' field, 'getopt'

212 there are no more options. For unrecognized options, or options
213 missing arguments, 'optopt' is set to the option letter, and '?' is
214 returned.
215
216 The OPTS string is a list of characters which are recognized option
217 letters, optionally followed by colons, specifying that that letter
218 takes an argument, to be placed in 'optarg'.
219
220 If a letter in OPTS is followed by two colons, its argument is
221 optional. This behavior is specific to the GNU 'getopt'.
222
223 The argument '--' causes premature termination of argument
224 scanning, explicitly telling 'getopt' that there are no more
225 options.
226
227 If OPTS begins with '-', then non-option arguments are treated as
228 arguments to the option '\1'. This behavior is specific to the GNU
229 'getopt'. If OPTS begins with '+', or POSIXLY_CORRECT is set in
230 the environment, then do not permute arguments. */
