* @brief Small stand-alone implementation of the printf family of functions

* a very limited resources.
*
* @note the implementations are thread-safe; re-entrant; use no functions from

* Prints/send a single character to some opaque output entity

* for linking against the library, if your toolchain does not support discarding unused functions)
*
* @note The output could be as simple as a wrapper for the `write()` system call on a Unix-like
* system, or even libc's @ref putchar , for replicating actual functionality of libc's @ref printf
* function; but on an embedded system it may involve interaction with a special output device,
* like a UART, etc.
*
* @note in libc's @ref putchar, the parameter type is an int; this was intended to support the
* representation of either a proper character or EOF in a variable - but this is really not
* meaningful to pass into @ref putchar and is discouraged today. See further discussion in:
