/*
* PSn00bSDK internal debug logger
* (C) 2022 spicyjpeg - MPL licensed
*
* This file provides the (admittedly minimal) logging system used by all
* PSn00bSDK libraries. Log messages and warnings are issued using the
* _sdk_log() macro and collected into a buffer, whose contents can be flushed
* by calling _sdk_dump_log() (by default this is done by VSync()). Logging is
* only enabled in debug builds of libpsn00b.
