Header file best practices for typedefs


Header file best practices for typedefs

This might help you I'm programming on a project which sounds like it uses the common.h method. It works very well for that project.
There is a file called ForwardsDecl.h which is in the pre-compiled header and simply forward-declares all the important classes and necessary typedefs. In this case unique_ptr is used instead of shared_ptr, but the usage should be similar. It looks like this:

Hope this helps In C you can only declare a variable at the start of a block. Your line:
code :
Integer *i = (Integer *)v->innerValue;
case INTEGER:
{
    Integer *i = (Integer *)v->innerValue;
    return i->value % hash->capacity;
}

This might help you If this is for some one-off code: sure, use typedefs, why not?
But code rarely is. And the problem with reusable code (or code that will, potentially, at some future point be reused) is: there are 1000 different ways of using it wrongly. Don’t artificially add reasons 1001–1255.

should help you out BOOL, CHAR, LPSTR and similar entirely-capitalized-types are (usually) Microsoft-defined types. The documentation states which headers are needed in order to get the correct definitions.

hop of those help? There's no hard rule that a header file with a given name has to have a corresponding source file of the same name.
If your header only has struct type definitions and typedefs then there's no need for there to be a corresponding .c file. If the file had function or global variable declarations then they would need to be defined in a .c file somewhere, however that file doesn't have to have the same name as the .h file.

Any of those help If you have concerns about the design, why don't you move the typedef to its own .h file? Just wrap it between the proper #ifndef... #endif
In this way the compiler will see it only once.
