I haven't actually done this for Informix-4GL (and ESQL/C), but I did it for Oracle's embedded SQL. Basically, I just created a header file that looked like: extern "C" { void _iqdclcursor(...); ... } This way, I didn't have to figure out the types of the parameters. I got the names of all the functions out of an nm listing on the library which was linked to. In Informix-ESQL/C's case, I believe this would be libsql.a in /usr/informix/lib. Then I went on to write C++ classes that directly called these functions, so I could avoid the embedded SQL entirely. One of these days, I intend to do the same for Informix-ESQL/C, mostly because I am growing tired of the limitations of 4GL.
