Constants ¶
const ( OSWindows = "windows" OSDarwin = "darwin" OSDragonfly = "dragonfly" OSFreebsd = "freebsd" OSLinux = "linux" OSNacl = "nacl" OSNetbsd = "netbsd" OSOpenbsd = "openbsd" OSSolaris = "solaris" )
These are the names of the operating systems recognized by Go.
Variables ¶
var CurrentPID = os.Getpid()
CurrentPID returns the process id of the caller.
var OSUnix = []string{ OSDarwin, OSDragonfly, OSFreebsd, OSLinux, OSNacl, OSNetbsd, OSOpenbsd, OSSolaris, }
OSUnix is the list of unix-like operating systems recognized by Go. See http://golang.org/src/path/filepath/path_unix.go.
