FDS mix fds_record_find_by_key() and fds_record_find()

[bart]

Hi, I was wondering if it's safe to do something like:

uint16_t recordKey = 15;
fds_record_desc_t desc;
fds_flash_record_t flashRecord;
fds_find_token_t outerToken;
fds_find_token_t innerToken;
memset(&outerToken, 0x00, sizeof(fds_find_token_t));


while (fds_record_find_by_key(recordKey, &desc, &outerToken) == FDS_SUCCESS) {
    fds_record_open(&desc, &flashRecord);
    uint16_t fileId = flashRecord.p_header->file_id;
    fds_record_close(&recordDesc);
    
    memcpy(&innerToken, &outerToken, sizeof(fds_find_token_t));
    while (fds_record_find(fileId, recordKey, &desc, &innerToken) == FDS_SUCCESS) {
        fds_record_open(&desc, &flashRecord);
        // Read the record.
        fds_record_close(&recordDesc);
    }
}

Hi,

I don't see any problems with this. Was it something specifically you were wondering about? 

To search for the next record with the same key in the file, call the function again and supply the same fds_find_token_t structure to resume searching from the last record that was found.

Is this what you're asking about?

In this case, finding all records for each found file_id, of given record_key.

Was asking mostly because of the warning: Never reuse the same token to search for different records.

You can alternatively have one token that you zero-initialize between each search for a new record.
