code complete cannot list the lua's function

<< < (2/2)

Ok, does it a .c file?
Another question is:

--- Code: ---int (bar_not_visible)();

--- End code ---
Do you think this is a valid C function declaration? I don't.

Freem:
It is an uncommon style, but I think it is valid.

In short, when you declare a callback, you declare a function pointer. So, a pointer which know the address of a function (I know that you perfectly know that, I am just going step by step to make things clear as best as I can).

For a classic variable, we use this:

--- Code: ---int foo;
--- End code ---
For a classic pointer:

--- Code: ---int *pfoo;[code]

For function pointers:
[code]int (*pbar)(void);
--- End code ---
So there are no reasons to think removing the pointer operand is not legal.
In fact, we could probably say that removing parenthesis is just a shortcut for easier read, and the parenthesis write is the good one.

To conclude, I have tried a very little program (which do nothing) and compiled it with "gcc foo.c -ansi" and it gaves me no error or warning.
Here it is:

--- Code: ---int (bar_not_v)();
int (bar_v)();

void main()
{
bar_v();
bar_not_v();
}

int bar_not_v()
{
}

int (bar_v)()
{
}

--- End code ---

i am doing a lua binding library for c++, so i often need to call the lua's C API to achieve some features :P

Still not clear about your idea. If you would like to show C API, should should have C code parsed by the CC's parser. Where is you C API declaration? Please give more details.

--- End quote ---

the C API declarations are in the Lua's header files
for example:

--- Code: ---// in lua.h
LUA_API lua_State *(lua_newstate) (lua_Alloc f, void *ud);

--- End code ---
