My googling leads to quite reasonable whitepaper: http://www.cs.umd.edu/~pugh/com/ Some quotes from there: "Is provided on multiple platforms (Microsoft® Windows®, Windows 95, Windows NT�, Apple® Macintosh®, and many varieties of UNIX®)" "It is important to note that COM is a general architecture for component software. Although Microsoft is applying COM to address specific areas such as controls, compound documents, automation, data transfer, storage and naming, and others, any developer can take advantage of the structure and foundation that COM provides." "For any given platform (hardware and operating system combination), COM defines a standard way to lay out virtual function tables (vtables) in memory, and a standard way to call functions through the vtables. Thus, any language that can call functions via pointers (C, C++, Smalltalk, Ada, and even BASIC) all can be used to write components that can interoperate with other components written to the same binary standard." "IDL is only a tool for the convenience of the interface designer and is not central to COM's interoperability. It simply saves the developer from manually creating header files for each programming environment and from creating proxy and stub objects by hand." -- WBR, SD. ------------------------------------------------------------------------------ Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
