Obtaining the actual size of the underlying storage of the buffer can be very useful in various scenarios. Long running programs which write and read large amounts of data to buffers might have to recycle buffers in order to avoid holding onto potentially huge buffers. For example, a piece of code which buffers a lot of data in a buffer might need to release the big buffer and start again with a smaller buffer after it finished processing the huge amount of data. In cases where pools of bytes.Buffer are used, being able to check the size of the allocated data can be very useful. Instead of forking bytes.Buffer or writing new code, we can export the Cap() method.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
