Typically L{ListenFDs.fromEnvironment} should be used to construct a new instance of L{ListenFDs}. @cvar _START: File descriptors inherited from systemd are always consecutively numbered, with a fixed lowest "starting" descriptor. This gives the default starting descriptor. Since this must agree with the value systemd is using, it typically should not be overridden. @ivar _descriptors: A C{list} of C{int} giving the descriptors which were inherited. @ivar _names: A L{Sequence} of C{str} giving the names of the descriptors which were inherited. _descriptors_namesNenvironstartreturncD|ddlm}|}||j}tt |dkr t ||}t|}ng}d}t|t|kr |gdS|||S)a @param environ: A dictionary-like object to inspect to discover inherited descriptors. By default, L{None}, indicating that the real process environment should be inspected. The default is suitable for typical usage. @param start: An integer giving the lowest value of an inherited descriptor systemd will give us. By default, L{None}, indicating the known correct (that is, in agreement with systemd) value will be used. The default is suitable for typical usage. @return: A new instance of C{cls} which can be used to look up the descriptors which have been inherited.
