Go to definition of a C function in a different file in Notepad++

While editing a C project on Notepad++ 5.6.7 (Unicode) with the SourceCookifier plugin, I can press Ctrl+Shift+Enter to go to the definition of a function which the cursor is on, but only if it is in the same file.

How can I go to its definition if it's in another file e.g. an extern, either natively or using SourceCookifier (preferred), or another plugin?

Solution 1:

Simply drag and drop your top level source folder into the SourceCookifier window. Additionally pressing SHIFT, CTRL or ALT while dropping will speed up everything, since no tags are shown in the tree view then. Check out the short manual and start using session files.

Solution 2:

I'm not a regular Notepad++ user, but the OpenCTags project at sourceforge looks promising.
