NULL handling

[stephanearnold]

Hello,

While writing an interpreter in C, I have thought of a suggestion for
some new keywords that would help to reduce C application complexity:

- nullable
- notnullable

I have a bunch of sept_get_XXX functions that return a pointer to a
struct, namely sept_Type*.
I have defined 'nullable' and 'notnullable' as empty macros in the
main .H file.

Now I defined my functions prototypes as follows:

inline notnullable sept_get_dict(void);
inline notnullable sept_get_list(void);

And I think I will use these macros in my source tree even for
function arguments, like this:

int my_func(nullable sept_Foo* foo, notnullable gchar* msg);

Why doesn't exist such a functionality in standard C/ or in specific
compilers?
Has my idea a chance to live, or is there no way to create such
keywords?
By the way, I have noticed they tend to make my source code difficult
to read,
but I will strive and continue to use it until I find a better way to
handle such informations.

Regards,
Stéphane A.

As seen here there was only one, accompanied by two more from
plonkees that were never allowed on my system.

Of course this still doesn't excuse the impatient re-entry.
