Reference to Design Patterns in ANSI C?



Can you point me to a reference of design patterns in Standard C (C89 or C99)? (Not C#, not C++.)




Consider a “disposable” keyword in C#

Following from Nick's answer, I suggest that you learn how to implement cplusplus-like things using C (e.g., a C struct with a pointer to a table of function pointers, emulates a C++ class with virtual functions), which means understanding how C++ is implemented by the compiler.

Once you've done this then you'll be able to read design patterns for C++ and implement them using C..

If you need information about real-time embedded C design patterns i can recommend the two books.
  • "Real-Time Design Patterns: Robust Scalable Architecture for Real-Time Systems" (Douglass, Bruce Powel | Elsevier | 1th Edition | 2002) and
  • "Design Patterns for Embedded Systems in C: An Embedded Software Engineering Toolkit" (Douglass, Bruce Powel | Elsevier | 1th Edition | 2011)
Some of the higher-level patterns depend on an "emulation" of object-oriented features like mentioned before.

The patterns are described very well (UML diagrams, examples).

I like the discussions of the "forces" (What has to be considered?) which influence the context after applying the patterns..
