Description:

The Data Display Debugger (DDD) is a common graphical user interface
for GDB, DBX, and XDB, the popular UNIX debuggers. Besides
``classical'' front-end features such as viewing source texts, DDD
provides a graphical data display, where data structures are displayed
as graphs. A simple mouse click dereferences pointers or views
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, Java, 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, search, and completion capabilities. DDD
has been designed to compete with well-known commercial debuggers
