Seen that way, resources are over-engineered. The basic compiler feature we weant is something like:
const char blob[] = __include_binary__("blob.dat");
But if I could do that, then probably the next thing I would do is invent some macro-magic to provide a resource-like namespace on top of the feature.- display an icon for an executable
- automatic localisation of application menus etc.
So FindResource() takes three parameters: a type (icon, string, dialog, bitmap, menu etc), a name, and a language ID. That means that changing the language ID can transparently select a different UI layout and text as required.
Meanwhile Explorer (and its ancestor Program Manager) will display the first icon in the resource file as the default program icon.
Resources are just a separate section within the PE executable format.
So it sounds like the critical thing that Windows resources have over the thing I outlined is that they and their namespaces are relatively transparent to external tools such as the Program Manager.
The critical thing is that MS could impose a standard. Anyone can write tools to put such a section to their ELF binaries. But it would be useless because then no one would know to read it.
This was already like that on the 16 bit days.
For example, with Turbo Pascal for Windows, you only needed to do, after generating the resources via the resource compiler
{$R resource name}
and then make use of FindResource/LoadResource/LoadFromResourceName[0]: (shameless plug) http://stackoverflow.com/questions/8923097/compile-a-binary-...
Interestingly the X Window System took the opposite approach for its images. Rather than making C accommodate their images, they made their images accommodate C! https://en.wikipedia.org/wiki/X_BitMap and https://en.wikipedia.org/wiki/X_PixMap are both image formats that consist of C code.
