Debugger Concepts

To build on the Visual Studio debug package, you need to be familiar with the architectural concepts used in designing the package.

In This Section

• Debug Session
  Explains the role of a session in the debugging architecture.

• Servers (Visual Studio SDK)
  Defines what a server is in terms of debugging architecture, in both abstract and physical terms.

• Port Suppliers
  Defines what a port supplier is in terms of debugging architecture.

• Ports
  Defines what a port is in terms of debugging architecture.

• Processes
  Defines what a process is in terms of debugging architecture.

• Program Nodes
  Defines a program node in terms of debugging architecture, including how it can identify itself and the process it is running in.

• Programs
  Defines a program in terms of debugging architecture.

• Threads
  Defines the characteristics of threads in terms of debugging architecture.

• Stack Frames
  Defines a stack frame in terms of debugging architecture. A stack frame is an abstraction of a stack that provides the execution context of a thread.

• Modules
  Defines a module, in terms of debugging architecture, as a physical container of code, such as an executable file or a DLL.

• Breakpoints (Visual Studio SDK)
  Defines the three types of breakpoints—pending, bound, and error—in terms of debugging architecture.

• Debugger Contexts
  Explains how the debug engine (DE) operates simultaneously within code, documentation, and expression evaluation contexts. Describes, for each of the three contexts, the location, position, or evaluation relevant to it.

• Debugger Components
  Provides an overview of the Visual Studio Debugging components, which include the debug engine (DE), expression evaluator (EE), and symbol handler (SH).

• Debugging Tasks
  Contains links to various debugging tasks, such as launching a program and evaluating expressions.
