I have a large code written in C, but I did not write all

  • 0

I have a large code written in C, but I did not write all of it myself. I wish to create an overview of the call structure in the code for reference. That is: I wish to know what (non-standard) functions are called by the different functions in the code, and thus create a hierarchy or a tree of the different functions. Are there any free, Unix compatible programs (that means no Visual Studio, but a Vim plugin or such would be neat) that can do this, or will I have to write something that can do this myself?
