如何定义一个用于struct array C的宏

Question

I've defined a macro to set my values(C code), for example:

.h file

typedef struct {
    uint8_t details;
    uint8_t info[20];
} values_struct;

#define INIT_VALUES_STRUCT(X) values_struct X = {.details = 0x00, .info = { 0x01 } }

.c file

INIT_VALUES_STRUCT(pro_struct);

but I need to set a "struct array" like:

values_struct pro_struct[10];

and to set default values with a macro, it's possible and how I can do that?

Answer 1

Redefine that macro as

#define INIT_VALUES_STRUCT {.details = 0x00, .info = { 0x01 } }

And then you can have

struct values_struct pro_struct = INIT_VALUES_STRUCT;
struct values_struct pro_struct_arr[] = { INIT_VALUES_STRUCT,
                                          INIT_VALUES_STRUCT,
                                          INIT_VALUES_STRUCT };

Why make it complicated with macros when the following works:

#include <stdio.h>
#include <stdint.h>
struct x {
    uint8_t details;
    uint8_t info[2];
};
int main(void) {
   struct x arr[2] = {
       { 1, {5, 6}},
       { 3, {4, 7}}

    };
    // your code goes here
    return 0;
}
