Detect unused struct members

Hi,

I've noticed that CLion successfully detects struct members not being used when selecting "find usages".

Is it possible to perform code analysis /cleanup and detect struct members not being used/used for write only?

For example:

#include <stdio.h>

typedef struct
{
    int a;
    int b_unused;
    int c_writeOnly;
} test_t

int main()
{
    test_t test;
    test.a=1;
    test.c_writeOnly=2;
    printf("Test: a=%d", test.a);

    return 0;
}
