Man
Using the man ioslave you are able to read the man pages installed on your system. It is easy to use:
man: 	 See the sections of the manual, click to find the rest.
man:/ fopen 	 See the man page of fopen.
man:/ fopen(3) 	 See the man page of fopen in section 3.
man:/ (3) 	 See the index of section 3.
man:/intro(3) 	 See the introduction of section 3.
If there are more than one man page of the name that you have entered, you will get a list where you can choose the man page that you want to see.
There is also a shortcut: #fopen, which has the same effect as above.
If you do not find all your man pages, adjust the configuration file /etc/manpath.config (or a file of a similar name depending on your distribution) or adjust the environment variables MANPATH and MANSECT.
As with any other ioslave, it is possible to enter a , like man:/socket in any application. Try it in and you will see the man page in format.
