dm_arg_read Function

public function dm_arg_read(args, callback) result(rc)

Uses

  • proc~~dm_arg_read~~UsesGraph proc~dm_arg_read dm_arg_read module~dm_version dm_version proc~dm_arg_read->module~dm_version

Reads all arguments from command-line and prints error message if one is missing. Returns the error code of the first invalid argument.

The function also parses the command-line arguments for -v/--version to display the current application and library version, and -h/--help to output all available command-line arguments. If one of these arguments is passed, dm_stop(0) is called afterwards.

Optional argument callback is a routine that outputs the version information.

The function returns the following error codes:

  • E_EMPTY if array of arguments is empty.
  • E_ARG_INVALID if an required argument has not been passed.
  • E_ARG_NO_VALUE if an argument has been passed without value.
  • E_ARG_TYPE if an argument has the wrong type.
  • E_ARG_LENGTH if the length of the argument is wrong.
  • E_ARG_UNKNOWN if an unknown argument has been passed.
