For any file of styles:

• /home/name/project/src/blah_blah/foo/bar.h - path has src folder
• /home/name/project/include/blah_blah/foo/bar.h - path has include folder
• /home/name/project/some_project/some_project/blah_blah/foo/bar.h - path has a folder some_project twice in a row
• /home/name/blah_blah/foo/bar.h - none of the above

this snippet will generate def guards of form:

#ifndef BLAH_BLAH_FOO_BAR_H_
#define BLAH_BLAH_FOO_BAR_H_
// you selection is copied here
#endif  // BLAH_BLAH_FOO_BAR_H_

It will also copy the code you have selected between the markers.
