Function toUnsafeChar

cgi.go:371–373

toUnsafeChar returns a *C.char pointing at the backing bytes the Go string. If C does not store the string, it may be passed directly in a Cgo call (most efficient). If C stores the string, it must be pinned explicitly instead (inefficient). C may never modify the string.
