Re: inline function

Yes. It is a macro. I am not well versed in C.

For understanding my needs you would have to read the README at https://github.com/fbuihuu/libtree

I have to create a compare function as a callback function in RPG (as RPG in my main programming language). The callback function gets two nodes. Each node is embedded in a user defined data structure. The function calculates the beginning of the user defined data structure by using the embedded node, some sizes and the offsetof macro. Actually I don't know how this works as I have seen it the first time today. But somehow it works.

From my understanding, rbtree_container_of is a macro rather than a function (although it may seem to share some function attributes). In what way would you hope to use rbtree_container_of in an RPG program/module?

The enum doesn't seem to be the problem.

I now tried it with __inline instead of inline. That at least compiled.
Google says that __inline is vendor/implementation specific.

I think I'll leave it at that.

But now I got another problem. The C header file defines a function:

# define rbtree_container_of(node, type, member) \
((type *)((char *)(node) - offsetof(type, member)))


This is a function I must use in my RPG program. How to do that?

It seems I am out of luck. Any ideas?

Thanx so far.

Mihael

I wonder if it's the enum that's actually presenting you with a
problem. How do the other static inline's compile? All good? Some
good? (Sorry, I lack a C compiler when I'm at work, and I lack i6.1
altogether.

No, inline without static gives the same error messages.

This is the source I try to compile.

Does it work if you remove static?

2011/2/1 Schmidt, Mihael <Mihael.Schmidt@xxxxxxxxxxx>:

Hi,

I have some problems compiling a source with the following function:

static inline enum rb_color get_color(const struct rbtree_node

*node)

{
       return node->color;
}

The error messages are:

CZM0166 : Definition of function inline requires parentheses.
...
CZM0485 : Parameter declaration list is incompatible with declarator

for inline.

...

If I remove inline everything compiles just fine.

Any idea?
