Description:

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.
