stream-nl ( stream -- )
Factor handbook » Input and output » Streams » Stream protocol

Prev:	stream-write ( data stream -- )
Next:	stream-seekable? ( stream -- ? )

Vocabulary
io

Inputs

stream

an output stream

Outputs
None

Generic word contract
Writes a line terminator. If the stream does buffering, output may not be performed immediately; use stream-flush to force output.

Notes
Most code only works on one stream at a time and should instead use nl; see Default input and output streams.

Errors
Throws an error if the I/O operation fails.
