C++ (Cpp) GTHTTP_createTimestampHash Examples

Example #1

File: gt_http.c Project: node-migrator-bot/node-guardtime

int GTHTTP_createTimestampData(const unsigned char *data, size_t data_len,
                               const char *url, GTTimestamp **timestamp)
{
    int res = GT_UNKNOWN_ERROR;
    GTDataHash *hash = NULL;

    if (data == NULL || url == NULL || timestamp == NULL) {
        res = GT_INVALID_ARGUMENT;
        goto cleanup;
    }

    res = GTDataHash_create(GT_HASHALG_DEFAULT, data, data_len, &hash);
    if (res != GT_OK) {
        goto cleanup;
    }

    res = GTHTTP_createTimestampHash(hash, url, timestamp);
    if (res != GT_OK) {
        goto cleanup;
    }

cleanup:

    GTDataHash_free(hash);

    return res;
}
