Hello,

  I'm trying to save the pid (an integer) to a file :

file, _ := os.OpenFile("tmp/camo.pid", os.O_CREATE, 0600)

file.WriteString(string(os.Getpid()))

But the i can convert properly the integer to a string, i just get the ASCII caracter corresponding to the number

Thanks

strconv.FormatInt and strconv.Atoi convert a string to an integer.

Which function would do the opposite ?

http://golang.org/pkg/strconv/#Itoa

(Did you read the package docs?)

FormatInt is int to string. There is a shorthand, itoa:
http://golang.org/pkg/strconv/#Itoa

you can also use formatted printing (e.g. if you have more than just
the number):

fmt.Fprint(file, "%d", os.Getpid())

You want to do strconv.Itoa(os.Getpid())  instead of string(...)
