Use CScope to find function calls (NOT definitions) (C/C++)

I need to find function calls in my C and C++ codes. When I was looking for some suitable software, I found CScope. It looks pretty well, the only problem is, that I can't find a way how to find just function calls with it.

 0 Find this C symbol:
 1 Find this function definition:
 2 Find functions called by this function:
 3 Find functions calling this function:
 4 Find this text string:
 5 Change this text string:
 6 Find this egrep pattern:
 7 Find this file:
 8 Find files

I thought about finding all symbols (cscope -L0) and then removing definitions (cscope -L1), but it means, that codes will be parsed 2x and I'm afraid it's going to be too slow.

Is there any better, "original", way to do this with CScope?

Solution

  • Use the option -L3 to ask for functions that call a specific function.
