      public IOStreamEmuUnixFileHandle(PcodeMachine<byte[]> machine, CompilerSpec cSpec, InputStream input, OutputStream output)
      Construct a proxy for a host resource

      WARNING: Think carefully before proxying any host resource to a temperamental target program.

      Parameters:
      machine - the machine emulating the hardware
      cSpec - the ABI of the target platform
      input - the stream representing the input side of the descriptor, if applicable
      output - the stream representing the output side of the descriptor, if applicable

  • Method Details

      public static IOStreamEmuUnixFileHandle stderr(PcodeMachine<byte[]> machine, CompilerSpec cSpec)
      Construct a proxy for the host's standard error output
      Parameters:
      machine - the machine emulating the hardware
      cSpec - the ABI of the target platform
      Returns:
      the proxy's handle
