+ <func_name_in_app> = <dll_name>.<func_name_in_dll>
+ <func_name_in_app> = <dll_name>.<number>
+ <dll_name>.<func_name_in_dll>
+ <dll_name>.<number>
+ Furthermore, the dll's name may or may not end with ".dll", which
+ complicates the parsing a little. Normally the dll's name is
+ passed to def_import() in the "module" parameter, but when it ends
+ with ".dll" it gets passed in "module" sans ".dll" and that needs
+ to be reappended.
+
+ def_import gets five parameters:
+ APP_NAME - the name of the function in the application, if
+ present, or NULL if not present.
+ MODULE - the name of the dll, possibly sans extension (ie, '.dll').
+ DLLEXT - the extension of the dll, if present, NULL if not present.
+ ENTRY - the name of the function in the dll, if present, or NULL.
+ ORD_VAL - the numerical tag of the function in the dll, if present,
+ or NULL. Exactly one of <entry> or <ord_val> must be
+ present (i.e., not NULL). */
