static int	vsnprintf (char *buffer, std::size_t size, const char *format, va_list args)
	Format string with arguments into buffer.
static int	snprintf (char *buffer, std::size_t size, const char *format,...)
	Format string with arguments into buffer.

Detailed Description

Lightweight printf implementation for ARM Cortex-M systems.

Supports only essential format specifiers to minimize code size. Perfect for embedded logging where full printf is overkill.
