<p>This function is only safe to call when no other logger initialization
|
||
function is called while this function still executes.</p>
|
||
<p>This can be upheld by (for example) making sure that <strong>there are no other
|
||
threads</strong>, and (on embedded) that <strong>interrupts are disabled</strong>.</p>
|
||
<p>It is safe to use other logging functions while this function runs
|
||
(including all logging macros).</p>
