• Resumen

  • A call graph is a text-based or graphical diagram showing which functions inside a code base involve which other functions. Accurate call graphs aid many debugging and software analysis tasks. For example, when viewing a code base for the first time, an examiner can tell from call graph wheter the code structure is flat or modular, and which functions are the busiest. Later in analysis, a call graph can be used to answer specific questions, such as which other functions within the code involve a specific function of interest.
