dhcpctl_new_object symbol lookup results got displayed correctly.
strlen symbol lookup results displayed correctly.
What was occurred? (as is)
Nothing is displayed currently because Global does not support symbol lookup. Since Global can only find definitions in GTAGSLIBPATH, when function definitions are not available but function declarations are available in the header files, the helpful information in the header files are ignored, just like the case with dhcpctl_new_object. User should be able to use symbol lookup in cases like this, because Global won't ignore useful information only available in the header files. This is especially useful in environment where only header files are exposed, but not the source, like Windows environment.
