/* The Stream class definition -- libwww
STREAM OBJECT DEFINITION
A Stream object is something which accepts a stream of text.
The creation methods will vary on the type of Stream Object. All creation methods
return a pointer to the stream type below.
As you can see, but the methods used to write to the stream and close it are pointed to
be the object itself.

These are the common methods of all streams. They should be self-explanatory, except
for end_document which must be called before free. It should be merged with free in
fact: it should be dummy for new streams.
The put_block method was write, but this upset systems which had macros for write().

Generic Error Stream
The Error stream simply signals an error on all output methods.
This can be used to stop a stream as soon as data arrives, for
example from the network.
