Using tags in emacs on windows

This requires you install the Gunwin32 tools or Cygwin, and describes how to build a tags table for the project you're working on, when using emacs to edit the source.

First you want to generate a file containing all the source files you want to have tagged. Go to the root folder of your project.

find . -regex ".*\(h$\|cpp$\)" > files.txt

Next pass this to etags to generate the tags table.

etags.exe - < files.txt 

Then when you're in emacs you need to visit the tags table, which will have been saved as TAGS.  M-x visit-tags-table  then browse to the folder where you made the TAGS file.  Now when you have the curser on some function you can type...  M-.  to go to a tag and  C-u M-.  to go to the next tag.  Once you're done, you can return to where you started with  M-*  Another useful function is  tags-apropos  Which will list all the tags matching a regex in a buffer.
