Coding standards

Code examples

The following code example fails the check and will give a warning:

typedef struct simpleStruct {
    int a;
} ss_t;

void example(void) {
    ss_t data;
    data.a = 0;
}

The following code example passes the check and will not give a warning about this issue:

extern void foo(int num);

typedef struct simpleStruct {
    int a;
} ss_t;

void example(void) {
    ss_t data;
    data.a = 0;
    foo(data.a);
}
