Question

I have a structure as shown below.

typedef struct
{
    attribute_code_t field_id;
    uint8_t instance_num;
    uint8_t length;
    uint8_t data[32];
    uint32_t crc_value;
}table_entry_t;

I want to populate the structure as follows.

entry->field_id = 54;;
entry->instance_num = 0;
entry->length = 4;
entry->data = 0xfdfcfefa;

It is giving me the error, error: incompatible types in assignment.at the last line.I am wondering what is the best way to do the above assignment.

Any help is appreciated.

Answer 1

The following code copies data to first 4 bytes of 32- byte.

tmpdata = 0xfdfcfefa;
memcpy(entry->data, &tmpdata, sizeof(uint8_t) *4);
