Pause()

void Pause

(

const void *

res = nullptr

)

Pauses a little while until the contended resource hopefully becomes available again. Depending on the number of calls this will either just do a light spin loop or it might put the thread to sleep. Furthermore offending threads might be logged to diagnose deadlocks or bad performance.

Parameters

[in]

res

The contended resource because of which Pause has to be called. Might be a nullptr.

Wait()

static void Wait ( Int  cnt )

_mm_pause()
