source: trunk/gsdl/src/mgpp/lib/getopt_old.h@ 2556

Last change on this file since 2556 was 2556, checked in by jrm21, 23 years ago

If we have getopt.h in here, gcc will find it instead of /usr/include/getopt.h
This seems to be a problem on some platforms (eg Suse), so it's been renamed.
(We still need it for win32 compilation...)

58 The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
59 of `struct option' terminated by an element containing a name which is
60 zero.
61
62 The field `has_arg' is:
63 no_argument (or 0) if the option does not take an argument,
64 required_argument (or 1) if the option requires an argument,
65 optional_argument (or 2) if the option takes an optional argument.
66
67 If the field `flag' is not NULL, it points to a variable that is set
68 to the value given in the field `val' when the option is found, but
69 left unchanged if the option is not found.
70
71 To have a long-named option do something other than set an `int' to
72 a compiled-in constant, such as set a value from `optarg', set the
73 option's `flag' field to zero and its `val' field to a nonzero
74 value (the equivalent single-letter option character, if there is
75 one). For long options that have a zero `flag' field, `getopt'
76 returns the contents of the `val' field. */
