Easiest way to append to a file

[Frank Blechschmidt]

Hey,

I try to write a little logging package for my program.

It should create a file if it doesn't exist and append a given input (string) into this file.

Most functions I tried so far overwrite the textfile :(

func WriteEntry (logfiletype, entry string){
datestamp := time.Now()
datestampstring := datestamp.String()
datestampstring = datestampstring[0:10]
datestampstring = logfiletype + "-" + datestampstring
os.Chdir("../logs")
logfile,_ := os.Create(datestampstring)
logfile.WriteString(entry)
logfile.Close()
}

Thanks

Frank

Instead of os.Create better is probably os.OpenFile(name,
os.O_WRONLY|os.O_APPEND|os.O_CREATE, perm) in this case.

cf: http://golang.org/pkg/os/#OpenFile
