C - Temporary struct with memory allocation

This struct is supposed to have the infos for each item of a queue. 

struct tx_queue_item_t {
    //user input
    uint8_t priority;      
    uint8_t attempts;    
    uint8_t *buff;
    size_t size;
    uint32_t timeout;               //10ms base
    //system input
    uint8_t idNum;
    uint8_t attemptCount;
    uint32_t tickCountAtTx;         //to check for receive timeout
    enum tx_queue_status_t status;
};

I would like to know if I'm able to have 'temporary items' (temporary structs), which free their own memory usage when such item of the queue be considered as done/processed.

Is there a way to make this in C? malloc? Consider that I also want to access the values of variables by their names for each struct instance. And also in order I can know what is the total memory being used for such purpose (create temporary items).

Regards.

No. C does not have widely-implemented garbage collectors. You can use an external library like boehm-gc, but that may not be what you want.

The most portable solution would be to use malloc and free manually, or use a function to create and destroy your structure.
