I am using cscope to get familiar with all the keywords used in socket programming. I went to the directory with c files. I used cscope. and then I searched for AF_INET. I got this :
#define AF_FILE PF_FILE
#define AF_INET PF_INET
#define AF_AX25 PF_AX25
This was a full page. I only published part of it. Now I want to know from where this PF_INET is coming? what command I should use. I have seen a guy to double click on PF_INEt and using some command to find it. I don't know what the command is? Kindly help me in this.
The second thing is when i quit the page with :q command. I come to this page :
Global definition: AF_INET
File Line
0 socket.h 119 #define AF_INET PF_INET
Find this C symbol:
Find this global definition:
Find functions called by this function:
Find functions calling this function:
Find this text string:
Change this text string:
Find this egrep pattern:
Find this file:
Find files #including this file:
here the cursor is blinking at 0. If I want to search again something, how I will do? How to navigate from here. I tried to google it but unable to understand anything from the tutoials. Please help me in this regard as I am complete noob to linux operating system and c programming. Thanks in advance.

Select the type of search that you'd like to perform, type in your search term and hit Enter. At the top of the screen Cscope will display a list of results with the file, function, and line where the search term was found.
Exit cscope. If the first character of the text for which you are searching matches one of these commands, you can escape the command by entering a \ (backslash) before the character. Now move the cursor to the fifth menu item, Find this text string, enter the text out of storage, and press the Return key.
I agree that cscope documentation is not very clear.
Use tab to move to the interactive part. Type your symbol name in “find this C symbol” or “Find this egrep pattern” and validate pressing RETURN.
If you want to call it from vim, type :help if_cscop.txt; hoping it helps!
:cscope add your_cscope_database
:cscope find s [your_symbol]
This will make a new quickfix list. use :cn and :cp to navigate, :cnf and :cpf to navigate from file to file in the results, and :colder and :cnewer to restore previous quickfix lists.

To exit from cscope interactive prompt, type Ctrl-d. If you just want to rebuild cscope's database, and not invoke cscope's interactive prompt, pass it the -b option. I usually invoke cscope as cscope -bcqR.
As for jumping around in vim using cscope, it really depends on your vim config.
Most probably, jump to tag (Ctrl-]) will use cscope first, then ctags (see :help cst and :help csto). Use Ctrl-T to go back.
There are some useful mappings for cscope that you can find by typing :help cscope-suggestions in vim. After adding those mappings to your .vimrc, you will be able to jump to symbols using Ctrl-_ s, the calling function using Ctrl-_ c, etc...
You can access vim's cscope documentation by typing :help cscope.
