-// For backward compatibility, the 'pipe:' prefix can be omitted, and in
-// that case, qemu_pipe_open will add it for you.
-
-// On success, return a valid file descriptor, or -1/errno on failure. E.g.:
-//
-// EINVAL -> unknown/unsupported pipeName
-// ENOSYS -> fast pipes not available in this system.
-//
-// ENOSYS should never happen, except if you're trying to run within a
-// misconfigured emulator.
