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.

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'
