CScout is a source code analyzer and refactoring browser for collections of C programs. It can process workspaces of multiple projects (we define a project as a collection of C source files that are linked together) mapping the complexity introduced by the C preprocessor back into the original C source code files. CScout takes advantage of modern hardware advances (fast processors and large memory capacities) to analyze C source code beyond the level of detail and accuracy provided by current compilers, linkers, and other source code analyzers. The analysis CScout performs takes into account the identifier scopes introduced by the C preprocessor and the C language proper scopes and namespaces.

CScout as a source code analyzer can:

More importantly, CScout helps you in refactoring code by identifying dead objects to remove, and automatically performing accurate global rename identifier refactorings, and various function argument refactorings. CScout will automatically rename identifiers

Furthermore, CScout allows you to refactor the arguments of functions and macros, introducing new arguments, deleting existing ones, or changing their order.
