Return next long option.
Source position: getopts.pp line 46
function GetLongOpts( |
ShortOpts: String; |
LongOpts: POption; |
var Longind: LongInt |
):Char; |
Returns the next option found on the command-line, taking into account long options as well. If no more options are found, returns EndOfOptions. If the option requires an argument, it is returned in the OptArg variable.
ShortOptions is a string containing all possible one-letter options. (see Getopt for its description and use) LongOpts is a pointer to the first element of an array of Option records, the last of which needs a name of zero length.
The function tries to match the names even partially (i.e. --app will match e.g. the append option), but will report an error in case of ambiguity. If the option needs an argument, set Has_arg to Required_argument, if the option optionally has an argument, set Has_arg to Optional_argument. If the option needs no argument, set Has_arg to zero.
Required arguments can be specified in two ways :
Optional arguments can only be specified through the first method.
