No, because the typelib doesn't have the original argument types.  For
example, a "gulong" argument is represented by GI_TYPE_TAG_INT32 on 32
bit architectures and LLP64, and GI_TYPE_TAG_INT64 on LP64.

You should use the .gir files instead; the "ctype" may sometimes be
useful for your purposes, but note that things like GObject signals have
no original "ctype", so in the end you'll have to carry a .gir -> ctype
code mapping anyways.

This last bit is unfortunately hard - g-i is fairly strongly oriented
towards assisting bindings for higher level languages, and not the other
way around.
