Description

What is DDD, anyway? ==================== The Data Display Debugger (DDD) is a common graphical user interface to GDB, DBX, and XDB, the popular UNIX debuggers. Besides ``usual'' features such as viewing source texts and breakpoints, DDD provides a graphical data display, where data structures are displayed as graphs. A simple mouse click dereferences pointers or reveals structure contents, updated each time the program stops. Using DDD, you can reason about your application by viewing its data, not just by viewing it execute lines of source code. Other DDD features include: debugging of programs written in C, C++, Ada, Fortran, Pascal, Modula-2, or Modula-3; machine-level debugging; hypertext source navigation and lookup; breakpoint, backtrace, and history editors; preferences and settings editors; program execution in terminal emulator window; debugging on remote host; on-line manual; interactive help on the Motif user interface; GDB/DBX/XDB command-line interface with full editing, history, and completion capabilities. DDD has been designed to compete with well-known commercial debuggers.
