From 39042d7f7c4997af55474ebe4513c81f00732837 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Sat, 24 Aug 2019 15:01:16 -0700 Subject: [PATCH] os_sleep: Use nanosleep for POSIX versions 2008 and higher uClibc-ng optionally disabled deprecated POSIX functions like usleep, causing compilation failures. This switches to nanosleep while retaining support for older libcs that do not support nanosleep.
