MultiplexStream

class MultiplexStream

Bases: ostream

This is a special ostream that forwards the data that is written to it to any number of other sources, for instance other ostreams, or explicitly to a disk file or to system logging utilities. It’s a very handy thing to set Notify to refer to when running in batch mode.

MultiplexStream.__init__()

MultiplexStream.add_file()

Adds the given file to the multiplex output. The file is opened in append mode with line buffering. Returns false if the file cannot be opened.

MultiplexStream.add_ostream()

Adds the indicated generic ostream to the multiplex output. The ostream will receive whatever data is sent to the pipe.

MultiplexStream.add_standard_output()

Adds the standard output channel.

MultiplexStream.add_stdio_file()

Adds the given file, previously opened using the C stdio library, to the multiplex output.

MultiplexStream.add_system_debug()

Adds the system debug output the the multiplex output. This may map to a syslog or some such os-specific output system. It may do nothing on a particular system.

Presently, this maps only to OutputDebugString() on Windows.

MultiplexStream.flush()

Forces out all output that hasn’t yet been written.
