> Yes. - I got such an impression.

Correction:

* Is it more efficient to call the function "seq_putc" for the desired data processing
  for a single character than to pass it to the function "seq_printf" in a string?

* Will the required data transfer shrink a bit for the affected functions because of
  such a change?
  How do you think about to reduce the transmission for such tiny strings
  containing delimiters?
