logPaths is an (optional) list of strings to use as paths to test for writing. If the file can be created/written to,

Only the first logPaths entry that "works" will be used, later entries will be ignored.

Currently this will almost always return a WinLogger.

AddWinLogger adds a WinLogger to a MultiLogger. Note that this is a VERY generalized interface to the Windows Event Log.
|
||
|
|
|
||
|
|
If you require more robust logging capabilities (e.g. custom event IDs per uniquely identifiable event),
|
||
|
|
you will want to set up your own logger (golang.org/x/sys/windows/svc/eventlog).

identifier is a string to use to identify the added WinLogger in MultiLogger.Loggers.
|
||
|
|
If empty, one will be automatically generated.
|
||
|
|
|
||
|
|
A blank source will return an error as it's used as the source name. Other functions, struct fields, etc. will refer to this as the "prefix".

A pointer to a WinEventID struct may be specified for eventIDs to map extended logging levels (as Windows only supports three levels natively).
