Maybe it’s a little late (about 4 years), but here’s the best way i’ve found (for a c file): cut and paste the contents of the .c in the .h file, and for each function, put the cursor on it’s name and press Alt+Enter, and choose “Split function into declaration and definition”. this will keep … Read more
WINVER determines the minimum platform SDK required to build your application, which in turn will determine at compile time which routines are found by the headers. You can use this to verify, at compile time, that your application will work on Windows 2000 (0x0500), for example, or on Windows XP (0x0501). MSDN’s page on Modifying … Read more
If it is functions you have specialized, you can either put them in the .cpp file, or make them inline in the header. Like James points out, if you don’t make the functions inline, you still have to declare the specializations in the header. Otherwise the compiler doesn’t know it has to look for them … Read more
It’s to make sure your clients don’t hate you when they include your library header. If the header is brittle and subject to break on wrong inclusion order, it may appear to work in your environment when it isn’t first – since you include the headers you need – but fail to compile for client … Read more
A self-contained header file is one that doesn’t depend on the context of where it is included to work correctly. If you make sure you #include or define/declare everything before you use it, you have a self-contained header. An example of a non self-contained header might be something like this: —– MyClass.h —– class MyClass … Read more
How much effort are you willing to go to? There’s an obnoxiously obscure way to do it but it requires you to set up a dummy directory to hold surrogates for the system headers. OTOH, it doesn’t require any changes in any of your source code. The same technique works equally well for C code. … Read more
A self sufficient header file is one that doesn’t depend on the context of where it is included to work correctly. If you make sure you #include or define/declare everything before you use it, you have yourself a self sufficient header. An example of a non self sufficient header might be something like this: —– … Read more
Your first way of doing it means that in a.h, the existence of class B is known, but not its definition. This limits what you can do with B inside a.h. For example, you can have variables of type B *, but not variables of type B (because for a declaration of a variable of … Read more
Some say, we are using “.cc” as extension for C++ files to differentiate from C files (which has an extension “.c”), likewise we are using using “.hh” as extension for C++ header files to differentiate from C header files (which has an extension “.h”). That is exactly the reason. It is just to differentiate CPP … Read more
In a header file you have to include ALL the headers to make it compilable. And don’t forget to use forward declarations instead of some headers. In a source file: corresponded header file necessary project headers 3rd party libraries headers standard libraries headers system headers In that order you will not miss any of your … Read more
