Package ctags

A C programming language indexing and/or cross-reference tool

https://ctags.io/

Ctags generates an index (or tag) file of C language objects found in
C source and header files. The index makes it easy for text editors or
other utilities to locate the indexed items. Ctags can also generate a
cross reference file which lists information about the various objects
found in a set of C language files in human readable form. Exuberant
Ctags improves on ctags because it can find all types of C language tags,
including macro definitions, enumerated values (values inside enum{...}),
function and method definitions, enum/struct/union tags, external
function prototypes, typedef names and variable declarations. Exuberant
Ctags is far less likely to be fooled by code containing #if preprocessor
conditional constructs than ctags. Exuberant ctags supports output of
Emacs style TAGS files and can be used to print out a list of selected
objects found in source files.

Install ctags if you are going to use your system for C programming.
