** API for PR printf like routines. Supports the following formats
** %d - decimal
** %u - unsigned decimal
** %x - unsigned hex
** %X - unsigned uppercase hex
** %o - unsigned octal
** %hd, %hu, %hx, %hX, %ho - "short" versions of above
** %ld, %lu, %lx, %lX, %lo - "long" versions of above
** %lld, %llu, %llx, %llX, %llo - "long long" versions of above
** %zd, %zo, %zu, %zx, %zX - size_t versions of above
** %Id, %Io, %Iu, %Ix, %IX - size_t versions of above (for Windows compat)
** You should use PRI*SIZE macros instead
** %s - string
** %c - character
** %p - pointer (deals with machine dependent pointer size)
** %f - float
** %g - float
