Hi,
After some googling and running into the same problem myself, it would be nice if cflow could provide the following options:
1. List all line numbers of where the function is in fact called in the source file and not the line number for the definition of said function.
2. Have an option to only show the actual arguments that were passed to the function at that specific line where it was called ( don't print just the default function signature arguments ) .
3. Show all invocations of a function even if it is multiple times in another function
4. Allow some simple filtering to remove functions that no one cares about like standard libc functions such as "printf" , sprintf...etc
5. Allow keeping in certain structures like while( a != b ) , or a for () loop and then the function calls nested inside of it
All of these would help fill in the gaps that cflow has that requires writing custom scripts for parsing the output.
Thanks,
