fnet_sprintf()

This function outputs formatted text to the default stream and terminates the printed text by the line separator string. Its descriptor is defined by FNET_SERIAL_STREAM_DEFAULT.
The function takes one or more arguments. The first argument is a string parameter called the "format string". The optional arguments following format are items (integers, characters or strings) that are to be converted to character strings and inserted into the output of format at specified placeholders. The number of arguments following the format parameters should at least be as much as the number of format placeholders.
The syntax for a format placeholder is "%[Flags][Width][Length]Type".

• Flags can be omitted or be any of:
  • - : Left justify.
  • + : Right justify.
  • 0 : Pad with leading zeros.
  • space : Print space if no sign.
• Width is minimum field width. It can be omitted.
• Length is conversion character. It can be omitted or by any of:
  • h : Short integer.
  • l : Long integer.
• Type can by any of:
  • d, i : Integer.
  • u : Unsigned.
  • x, X : Hexadecimal.
  • o : Octal.
  • b : Binary.
  • p : Pointer.
  • c : Single char.
  • s : Char string.
  • n : Nothing.

Note

To save some bytes from all the hard coded strings the fnet_(s)printf() functions will expand all line feeds ("\n") inside the format string to CR LF ("\r\n"). So do not use "\r\n" in the format string - it will be expanded to "\r\r\n". It is save to add it via a parameter though, e.g. fnet_printf("%s", "\r\n");
This feature can be disable/enabled by the FNET_CFG_SERIAL_PRINTF_N_TO_RN configuration parameter.
