You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: builtin.go
    path of file: ./repos/goldfish/vendor/github.com/hashicorp/go-syslog
    
    the code of the file until where you have to start completion: // This file is taken from the log/syslog in the standard lib.
// However, there is a bug with overwhelming syslog that causes writes
// to block indefinitely. This is fixed by adding a write deadline.
//
// +build !windows,!nacl,!plan9
