From 07799e756c76ecd52cb01a812ba48b7d8ac67633 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 10 Oct 2005 11:49:49 +0200 Subject: [PATCH] [ALSA] Use getnstimeofday() Modules: Documentation,PCM Midlevel,Timer Midlevel,ALSA Core Use the standard getnstimeofday() function instead of ALSA's own one.
