getopt.h - Read command line options
|
||||
|
||||
AUTHOR: Gregory Pietsch
|
||||
CREATED Thu Jan 09 22:37:00 1997
|
||||
|
||||
DESCRIPTION:
|
||||
|
||||
The getopt() function parses the command line arguments. Its arguments argc
|
||||
and argv are the argument count and array as passed to the main() function
|
||||
on program invocation. The argument optstring is a list of available option
|
||||
characters. If such a character is followed by a colon (`:'), the option
|
||||
takes an argument, which is placed in optarg. If such a character is
|
||||
followed by two colons, the option takes an optional argument, which is
|
||||
placed in optarg. If the option does not take an argument, optarg is NULL.
|
||||
|
||||
The external variable optind is the index of the next array element of argv
|
||||
to be processed; it communicates from one call to the next which element to
|
||||
process.
|
||||
|
||||
The getopt_long() function works like getopt() except that it also accepts
|
||||
long options started by two dashes `--'. If these take values, it is either
|
||||
in the form
|
||||
|
||||
--arg=value
|
||||
|
||||
or
|
||||
|
||||
--arg value
|
||||
|
||||
It takes the additional arguments longopts which is a pointer to the first
|
||||
element of an array of type GETOPT_LONG_OPTION_T, defined below. The last
|
||||
element of the array has to be filled with NULL for the name field.
|
||||
|
||||
The longind pointer points to the index of the current long option relative
|
||||
to longopts if it is non-NULL.
|
||||
|
||||
The getopt() function returns the option character if the option was found
|
||||
successfully, `:' if there was a missing parameter for one of the options,
|
||||
`?' for an unknown option character, and EOF for the end of the option list.
|
||||
|
||||
The getopt_long() function's return value is described below.
|
||||
|
||||
The function getopt_long_only() is identical to getopt_long(), except that a
|
||||
plus sign `+' can introduce long options as well as `--'.
|
||||
|
||||
Describe how to deal with options that follow non-option ARGV-elements.
|
||||
|
||||
If the caller did not specify anything, the default is REQUIRE_ORDER if the
|
||||
environment variable POSIXLY_CORRECT is defined, PERMUTE otherwise.
|
||||
|
||||
REQUIRE_ORDER means don't recognize them as options; stop option processing
|
||||
when the first non-option is seen. This is what Unix does. This mode of
|
||||
operation is selected by either setting the environment variable
|
||||
POSIXLY_CORRECT, or using `+' as the first character of the optstring
|
||||
parameter.
|
||||
|
||||
PERMUTE is the default. We permute the contents of ARGV as we scan, so that
|
||||
eventually all the non-options are at the end. This allows options to be
|
||||
given in any order, even with programs that were not written to expect this.
|
||||
|
||||
RETURN_IN_ORDER is an option available to programs that were written 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 optstring parameter 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 `--' can cause
|
||||
getopt() and friends to return EOF with optind != argc.
