[go-nuts] diffrence between flush and write

The caller is your code. You code calls that method (also known as invoking the method)

Flush is a property of writer implementations that buffer their output. Buffering output means every write call may not result in a corresponding write call to the underlying writer. This can improve performance, but as the underlying writer is invoked less often it may not be immediately obvious that the underlying writer is having a problem (maybe out of disk space, maybe the TCP socket for disconnected).

The flush method will send any buffered data to the underlying writer unconditional and may expose any error with the underlying writer.

Flush is invoked by the close method on writers that buffer writes.

@Dave how can i buffer the output of a writer please help me with an
example

The gzip code that you are looking at is an example.

Or, I just typed "go buffer output of writer" into a search engine,
and the first link was to http://golang.org/pkg/bufio/ . That is
another example.

@Dave the writer of bufio package implements the buffer for io.writer type
, But writer of Gzip don't implements a buffer for io.writer it just write
to the io.writer embeding

It doesn't buffer the output in the same way, but it does buffer the
output. Look at the Flush method and think about what would happen if
it were never called.
