I usually dig in the c source code with cscope from method to method more than 4-5 level and I have to step between the methods back and forth.
How can I see the search history in cscope so I don't have to remember the previous method name. or it will be better if it's a stack.
Yes it does. The help explains this. [ Press ? in the main window.]
Ctrl+b - Step back in search history.
Ctrl+f - Step forward in search history.
I primarily use the cbrowser GUI frontend http://sourceforge.net/projects/cbrowser/ to cscope and it has a drop-down box where it remembers the last 15 queries.
Alternatively, if you use the Vim or Emacs/XEmacs editors they have cscope support built-in. I'm not familiar with how the Emacs integration works but in Vim it works pretty much like a regular tag-stack in that you can jump to symbol and then pop back to a previous symbol. Here's some information on the Vim integration http://cscope.sourceforge.net/cscope_vim_tutorial.html. There is some information on the emacs integration on the main cscope page http://cscope.sourceforge.net/.
At the cscope prompt you can type Ctrl-b to go back to your previous searches. If you move to
another field say "symbol search" from "definition search", you can repeat the query for the
same symbol by pressing Ctrl-y. HTH.
