macro to call lists

[sim fasaei]

Hej Guys
I have problem to make some macros to my own project I want to make some
Macro which it can make a several list automatically as example:
Pseudo code:
#define A 0x01
#define B 0x02
#define C 0x04
Etc..

#define ENABEL_A 1
#define ENABEL_B 0
#define ENABEL _C 2
etc…

If (ENABEL_A == 1 ) ADD_TO_LIST_1(A );
else ADD_TO_LIST_2(A );
etc…

result shud bee

LIST_1 {A,B,C,D}
LIST_2 {B,C,D,F}
LIST_3 {E,F,D,G} etc….

And when I call another macro RUN_TRUE_LIST_1

It should runs true each list and call a function like:
Calling(A);
calling(B);
calling (C); etc.

So first a macro to make my lists
Second a macro to runs trues those lists. Please help me.

What is the problem again?

What language are you using?

Im using C and the problem is :

Sorry about last message her is the problem?

I need a macro to make my_list, so when i call MAKE_MYLIST(Lis t1) it makes list1.
my_list{

list_1{elm1,elm 2,elm3},
list_2{elm4,elm 5,elm6},
list_3{elm5,elm 7,elm8},
}
Then i need a macro to add elements to specific list, so when i call ADD_ELM_TO_MYLI ST(List1,elm4) it adds elm4 to List_1.
And i need a macro to removes elements from specific list, so when i call REMOVE_ELM_FROM _MYLIST(List1,e lm4) it removes elm4 from List_1.
Then i need a macro to put an element from random list as parameter in a function , so when I call ACT_ON_THIS(Lis t1,elm2) it calls a function "action(elm 2)".

Do you expect MAKE_MYLIST to be called from executable code or do you expect this macro to expand into into a variable definition with an initializer?

I need a macro to make my_list, so when i call MAKE_MYLIST(Lis t1) it makes list1.

my_list{
list_1{elm1,elm2,elm3},
list_2{elm4,elm5,elm6},
list_3{elm5,elm7,elm8},
}

Are you sure? The macro expansion you show here is not valid C.

Some further questions:

• What is the data type for my_list?
• How did the macro know to use the name my_list?
• How did the macro know there were three items, and that they were named list_1, list_2, list_3?
• How did the macro know there were three subitems for each item, and how did it know what their names were?

And the big question -- why do you wish to do this with macros instead of C instructions?

Iexpect this macro to expand into into a variable definition with an initializer:


enum{
elm1=1,
elm2,
elm3,
elm4,
.
.
.
last_elm
} MY_ELM_ID


typedef struct
{
MY_ELEM_ID lists[];
} MY_ELM_LIST;

#define MAKE_MYLIST(nam e) \
const MY_ELM_LIST name[] = {

};
And yes thats a god question why not C?
My intention was to make those lists or list at compiling time, so I easily can add or removes list\lists or elements from a header file.
let us sig like a group of switches.

list_1, list_2, and list_3 from your reply #5 correspond to that description of MAKE_MYLIST.

• But where did my_list come from? It is an array of arrays.
• How did the macro know how many elms to put in each list?
• How did the macro know which elms to put in each list?

I can't be sure until I understand exactly what you're trying to do, but I suspect you would find it easier to accomplish this at execution time. Take a look at the Arrays Revealed article to see how to dynamically allocate a one-dimensional or two-dimensional array. (You will have to replace the C++ new keyword with a call to the malloc library function.)
