From man page for global:
-r, --reference, --rootdir
Print reference tags. Reference means the reference to a symbol which has definitions. With the -p option, print the root directory of
the project.
I have a use case where I want to know all function/method calls in my large source tree. I don't have all functions defined, but I would like to still know/find these symbols.
Is this possible? I have read that C++ parser seems to be on way to deprecation (!!), are there other means possible to seek out even undefined references?
Thanks.
