Frama-C API - Dpd

Dpd stands for 'dependence'. This object is used as a label on the edges of the PDG. There are three kinds of dependencies :

  • control dependency,
  • address dependency,
  • data dependency.

An edge can carry one or several kinds. A bottom edge means that there are no relation.
