# C references to Go

Go functions can be exported for use by C code in the following way:

	//export MyFunction
	func MyFunction(arg1, arg2 int, arg3 string) int64 {...}

	//export MyFunction2
	func MyFunction2(arg1, arg2 int, arg3 string) (int64, *C.char) {...}

They will be available in the C code as:

		var deps []*Action
		if a1.buggyInstall {
			// (*Builder).vet expects deps[0] to be the package
			// and deps[1] to be "fmt". If we see buggyInstall
			// here then a1 is an install of a shared library,
			// and the real package is a1.Deps[0].
			deps = []*Action{a1.Deps[0], aFmt, a1}
		} else {
			deps = []*Action{a1, aFmt}
		}
		for _, p1 := range p.Internal.Imports {
			deps = append(deps, b.vetAction(mode, depMode, p1))
		}

		log.Printf("too many periods in symbol specification")
		usage()
