About:
Protobuf-C is a pure C implementation of Google's Protocol Buffers data serialization format. It enables efficient data exchange across different systems and programming languages without requiring a C++ dependency. This library is ideal for embedded systems and environments where C++ is not available.
Key Features:
  • Pure C implementation
  • No C++ dependency
  • Cross-language compatibility
  • Low memory footprint
  • Code generation from .proto files
Use Cases:
  • Embedded systems development
  • Interoperability between C and other languages
  • Network communication protocols
  • Data serialization in resource-constrained environments
Alternatives:
  • protobuf (upstream) – Official Google implementation, requires C++
  • nanopb – Optimized for microcontrollers, minimal features
