Linking Rtt32.lib into the EXE
When Rtt32.lib is linked into the main program, other DLLs can access RTTarget-32's functions in the EXE if they are exported. This generally means that a module definition file has to be used when linking the EXE. The DEF file must list all functions (RTTarget native and Win32 emulation) needed by other modules with EXPORT directives. The advantage of this method is that only those parts of Rtt32.lib actually used by the application are linked. The disadvantage is that maintaining DEF files can be cumbersome. However, utility Makedef.exe can be used to automate DEF file maintenance (see section Utility MakeDef).
RTLoc's Dynamic Link Report (which must be explicitly enabled with option -Rd+) in the .LOC file can be used to analyze exactly which functions must be exported. All missing functions will be reported in warning messages. If you have exported functions not required by the application, they will be listed under unreferenced entrypoints at the end of the Dynamic Link Report.
Example program DLLDemo2 shows how to link Rtt32.lib and export RTTarget-32 functions to other DLLs.
