Is it possible to find calls to a function?

Hi,

I am using cscope for this purpose, but how hard is to develop this feature for clang_complete?

Hi,

it's not that easy. Making a call graph requires parsing all compilation units of the project, while clang_complete basically works only on the current one. Things are missing:

• notion of a project;
• indexing of the whole project;
• storage for parsing results ("who calls whom" in this case);
• interaction with such storage.

This subject was brought up several times over the years, but I don't remember successful tries (the tries are somewhere among the forks I think).

Not all is in forks, see clang-cache at least, there might be more.
