From 3c1efa0c92445638bbfa57c2e868c79f7d987fc3 Mon Sep 17 00:00:00 2001 From: Vijay Bellur Date: Thu, 20 Jun 2019 15:50:01 -0700 Subject: Replace usleep() with nanosleep() As usleep has been obsoleted, changed all invocations of usleep to nanosleep. From man 3 usleep: "4.3BSD, POSIX.1-2001. POSIX.1-2001 declares this function obsolete; use nanosleep(2) instead. POSIX.1-2008 removes the specification of usleep()." Added a helper function gf_nanosleep() to have a single place for handling edge cases that might arise from the conversion of usleep to nanosleep and allow the sleep to resume with right remaining value upon being interrupted.
