I would like to know any difference between ordinal and hint value in the native dlls? Anyone knows?
Ordinals can be thought of as the alternative (internal) name of a exported function (All exports have a ordinal and some only have the ordinal a.k.a. NONAME). They were common in 16-bit windows but not so much these days (The import/export tables are smaller if you don’t include the “string name”). They are slightly faster for the loader to look-up and are often used for undocumented functions. The downside is that they might not be stable from release to release.
The hint is used by the loader as a shortcut into the dll export table, if the hint offset does not match the expected function name the normal search is used.
