// This sml_buffer is used in two different use-cases.
//
// Parsing: the raw data is in the buffer field,
// the buffer_len is the number of raw bytes received,
// the cursor points to the current position during parsing
//
// Writing: At the beginning the buffer field is malloced and zeroed with
// a default length, this default length is stored in buffer_len
// (i.e. the maximum bytes one can write to this buffer)
// cursor points to the position, where on can write during the
// writing process. If a file is completely written to the buffer,
// cursor is the number of bytes written to the buffer.
