/* Describe the long-named options requested by the application.
|
||||
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
|
||||
of `struct option' terminated by an element containing a name which is
|
||||
zero.
|
||||
|
||||
The field `has_arg' is:
|
||||
no_argument (or 0) if the option does not take an argument,
|
||||
required_argument (or 1) if the option requires an argument,
|
||||
optional_argument (or 2) if the option takes an optional argument.
|
||||
|
||||
If the field `flag' is not NULL, it points to a variable that is set
|
||||
to the value given in the field `val' when the option is found, but
|
||||
left unchanged if the option is not found.
|
||||
|
||||
To have a long-named option do something other than set an `int' to
|
||||
a compiled-in constant, such as set a value from `optarg', set the
|
||||
option's `flag' field to zero and its `val' field to a nonzero
|
||||
value (the equivalent single-letter option character, if there is
|
||||
one). For long options that have a zero `flag' field, `getopt'
|
||||
returns the contents of the `val' field. */

Return the option character from OPTS just read. Return -1 when
|
||||
there are no more options. For unrecognized options, or options
|
||||
missing arguments, `optopt' is set to the option letter, and '?' is
|
||||
returned.
|
||||
|
||||
The OPTS string is a list of characters which are recognized option
|
||||
letters, optionally followed by colons, specifying that that letter
|
||||
takes an argument, to be placed in `optarg'.
|
||||
|
||||
If a letter in OPTS is followed by two colons, its argument is
|
||||
optional. This behavior is specific to the GNU `getopt'.
|
||||
|
||||
The argument `--' causes premature termination of argument
|
||||
scanning, explicitly telling `getopt' that there are no more
|
||||
options.
|
||||
|
||||
If OPTS begins with `--', then non-option arguments are treated as
|
||||
arguments to the option '\0'. This behavior is specific to the GNU
|

`getopt'. */

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

scanning, explicitly telling `getopt' that there are no more
