Here you have an example. It is not optimal, you could, for example,
take the brigade creation out of the loop and clean the brigade at the
end of each iteration, after you extracted the data.

apr_bucket_brigade *bb;
do {
   bb = apr_brigade_create(req->pool, req->connection->bucket_alloc);
   if (0 == bb)
        // error
   if (APR_SUCCESS != ap_get_brigade(req->input_filters, bb,
AP_MODE_READBYTES, APR_BLOCK_READ, 9216))
        // error
   extract data from bb;
} while (EOS not yet encountered in bb);
