I noticed that the boost library uses header files of (.hpp).
I am curious since most source files i see use normal .h header files.
Could there be any special instances which warrant use of .hpp instead of .h
Thanks

So ....
Is a loose convention for C++ header files, .tcc is a loose convention for C++ template with contents of filename .
To do this separation it is important to know, .H, etc .
A .h file would define only functions supported by C.

Include other includes in the header file if the contents of the header file uses types defined header file uses bool , then yes, it should include stdbool.h .

Sure - inside the header file put:

..then just print, the __FILE__ macro, and the __COUNTER__ macro.

Given a managed COM object and an associated tlb file, I would like to access it from some unmanaged C++ code WITHOUT using the TLB/import command. But use a header file.
Is there a way to extract a header file from a TLB?
Thanks

This will ensure that every time you compile the ... .
The OLE/COM Viewer allows you to save a TLB file as a header, C, or IDL file! Very cool! Thanks!
i am unsure why you do not want to use the import command.
I found it (on a whim).

Removing the header file just isn't an option (the function definition is in the .c / .cpp file) None of the above actually results in machine.
To do about it? You can't remove the code that you use .

If a header file (.h) included in the source file has also been included in a static library (.lib), what will happen?
Answer Snippets (Read the full thread at stackoverflow):
If the header declares things like global static.
I don't think anything will happen unless some objects have been instantiated in the header file header, so this is not a particularly special case.
