CVSROOT: /sources/certi
Module name: certi
Changes by: Eric NOULARD <erk> 08/10/30 10:49:29
Modified files:
RTIG : CMakeLists.txt Federation.hh FederationsList.hh
RTIG.cc main.cc Federation.cc
FederationsList.cc RTIG.hh
libCERTI : fed.hh fed.cc
Added files:
RTIG : RTIG.ggo RTIG_cmdline.c RTIG_cmdline.h
Removed files:
RTIG : CommandLine.ggo getopt1.c cmdline.c cmdline.h
getopt.c getopt.h
Log message:
Update RTIG command line option handling
and add a verbosity level handling in order to ease testing
and avoid to display FED file parse if verbosity is strictly less than
2.
The default level is 2 in order to keep backward compatibility

that
+ * wants an optional arg; if there is text in the current ARGV-element,
+ * it is returned in `custom_optarg', otherwise `custom_optarg' is set to zero.
+ *
+ * If OPTSTRING starts with `-' or `+', it requests different methods of
+ * handling the non-option ARGV-elements.
+ * See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+ *
+ * Long-named options begin with `--' instead of `-'.
+ * Their names may be abbreviated as long as the abbreviation is unique
+ * or is an exact match for some defined option. If they have an
+ * argument, it follows the option name in the same ARGV-element, separated
+ * from the option name by a `=', or else the in next ARGV-element.
+ * When `getopt' finds a long-named option, it returns 0 if that option's
+ * `flag' field is nonzero, the value of the option's `val' field
+ * if the `flag' field is zero.
+ *
+ * The elements of ARGV aren't really const, because we permute them.
+ * But we pretend they're const in the prototype to be compatible
+ * with other systems.
+ *
+ * LONGOPTS is a vector of `struct option' terminated by an
+ * element containing a name which is zero.
+ *
+ * LONGIND returns the index in LONGOPT of the long-named option found.
+ * It is only valid when a long-named option has been found by the most
+ * recent call.
+ *
+ * Return the option character from OPTS just read. Return -1 when there are
+ * no more options. For unrecognized options, or options missing arguments,
+ * `custom_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 `custom_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'.

- PERMUTE is the default. We permute the contents of ARGV as we scan,

- expect this.

- to expect options and other ARGV-elements in any order and that care about
- the ordering of the two. We describe each non-option ARGV-element
- as if it were the argument of an option with character code 1.
- Using `-' as the first character of the list of option characters
- selects this mode of operation.
-
- The special argument `--' forces an end of option-scanning regardless
- of the value of `ordering'. In the case of RETURN_IN_ORDER, only

-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.
-
- If LONG_ONLY is nonzero, '-' as well as '--' can introduce

- 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'
