typedef struct _mongoc_stream_t mongoc_stream_t
mongoc_stream_t provides a generic streaming IO abstraction based on a struct of pointers interface. The idea is to allow wrappers, perhaps other language drivers, to easily shim their IO system on top of mongoc_stream_t.
The API for the stream abstraction is currently private and non-extensible.
There are a number of built in stream types that come with mongoc. The default configuration is a buffered unix stream. If TLS is in use, that in turn is wrapped in a tls stream.
