CTREE is a command line utility providing analysis tools useful to software engineers tasked with tracking down problems or verifying a program's soundness. It is also an aid to understanding the structure of unfamiliar programs. As it works with standard C it finds most of its utility in embedded systems and older software.

CTREE comes with a comprehensive manual.

CTREE is is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative RTOS
https://sourceforge.net/projects/cortos-simple/ and PRTOS pre-emptive RTOS

  • Graphical tree showing the structure of a program's C source code. A tree is produced for each root of the program - main (), interrupt service routines, independent tasks running under an RTOS, and any vestigial uncalled functions;
  • Reverse tree that starts with a function and traces back all paths that lead to the function from the roots of the program;
  • Tree index showing the locations of each function in the tree;
  • Cross reference showing where each function is called;
  • List of uncalled functions;
  • Identification of possible recursive paths, multiple functions with the same name and duplicate functions.
