rcpputils: ROS 2 C++ Utilities

rcpputils is a C++ API consisting of macros, functions, and data structures intended for use throughout the ROS 2 codebase

This package currently contains:

Clang Thread Safety Annotation Macros

the rcpputils/thread_safety_annotations.hpp header provides macros for Clang's Thread Safety Analysis feature.

The macros allow you to annotate your code, but expand to nothing when using a non-clang compiler, so they are safe for cross-platform use.

To use thread safety annotation in your package (in a Clang+libcxx build), enable the -Wthread-safety compiler flag.

For example usage, see the documentation of this feature and the tests in test/test_basic.cpp

In rcpputils/find_library.hpp:

find_library(library_name): Namely used for dynamically loading RMW implementations.
- For dynamically loading user-defind plugins in C++, please use pluginlib instead.
