Question

I need help assigning a value to an array with in a structure. Your help is greatly appreciated:

typedef struct _temp_t {
     int16_t _values[4];
} TEMP_T;

void func() {
    TEMP_T *temps;
    int x = 5;

    temps._values[0] = x;
}

I’m getting an error :

 ...src/rodm/ucdCom.c:512: error: request for member '_values' in something not a structure or union

Your help is greatly appreciated!

Answer 1

TEMP_T *temps;

temps is a pointer, so it has no members, only structs and unions have members.

After you allocated memory for temps, you could set

temps->_values[0] = x;

Or you can declare temps as a TEMP_T,

TEMP_T temps;

and leave the rest of the code as is.
