twisted.python.systemd.ListenFDs : API documentation

ListenFDs provides access to file descriptors inherited from systemd.

Typically ListenFDs.fromEnvironment should be used to construct a new instance of ListenFDs.

Method	__init__
Class Method	fromEnvironment	No summary
Method	inheritedDescriptors
Class Variable	_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. (type: `int`)
Instance Variable	_descriptors	A `list` of `int` giving the descriptors which were inherited.

_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. (type: int)

_descriptors =

A list of int giving the descriptors which were inherited.

def __init__(self, descriptors): (source)

Parameters descriptors The descriptors which will be returned from calls to inheritedDescriptors.

@classmethod
def fromEnvironment(cls, environ=None, start=None): (source)

Parameters	environ	A dictionary-like object to inspect to discover inherited descriptors. By default, `None`, indicating that the real process environment should be inspected. The default is suitable for typical usage.
	start	An integer giving the lowest value of an inherited descriptor systemd will give us. By default, `None`, indicating the known correct (that is, in agreement with systemd) value will be used. The default is suitable for typical usage.
Returns	A new instance of `cls` which can be used to look up the descriptors which have been inherited.

def inheritedDescriptors(self): (source)

Returns The configured list of descriptors.
