Defining a New Stream

The following steps are required to define a new stream in C:

• Define low level functions (character reading, writing etc).
• Initialize and open your stream.
• Allocate memory needed for your particular stream.
• Initialize and install a Prolog stream with SP_make_stream() or SP_make_stream_context().
• Initialize additional fields. Some streams may require additional changes to the fields in the SP_stream structure than the default values set by SP_make_stream().

• Low Level I/O Functions:
• Installing a New Stream:
• The Internal Representation of a Prolog Stream:
