How to rename many variable names at once (C/C++)

Is there a tool that will allow me to rename a large number of variable names at once?

I have a large number of variables that I want to put into a C structure and therefore, I would need to add a parameter to the beginning of each name included in the structure.

Every half-decent IDE has a feature for this. You said that you're using Eclipse, so you can select the variable that you want to rename and then use the Refactor command to change the name in all your files.

sed with find, in a shell terminal, as in:

$ find /path/to/project/root -name "*.[ch]" -exec sed -ri 's/original_name/new_name/' {} \;

If you really want to do it at once, put a regular expression into your advanced search/replace function. ^(name1|name2|name3)$ ought to work. But no guarantee that it won't catch other things besides variable uses (in particular, the variable declarations). If you want that, you would have to work with something like Clang's tooling.
