rotate_lumberjack_windows.go

// Package rotate provides a rolling logger.
//
// Note that this is v2.0 of rotate, and should be imported using gopkg.in
// thusly:
//
//   import "gopkg.in/natefinch/rotate.v2"
//
// The package name remains simply rotate, and the code resides at
// https://github.com/natefinch/rotate under the v2.0 branch.
//
// rotate is intended to be one part of a logging infrastructure.
// It is not an all-in-one solution, but instead is a pluggable
// component at the bottom of the logging stack that simply controls the files
// to which logs are written.
//
// rotate plays well with any logging package that can write to an
// io.Writer, including the standard library's log package.
//
// rotate assumes that only one process is writing to the output files.
// Using the same rotate configuration from multiple processes on the same
// machine will result in improper behavior.
