Gregory Nutt fdd0dcc0b6 This commit adds internal versions of the signal interfaces: ... sigtimedwait() -> nxsig_timedwait() sigwaitinfo() -> nxsig_waitinfo() nanosleep() -> nxsig_nanosleep() The internal OS versions differ from the standard application interfaces in that: - They do not create cancellation points, and - they do not modify the application's errno variable Squashed commit of the following: sched/signal: Replace all usage of sigwaitinfo(), sigtimedwait(), and nanosleep() with the OS internal counterparts nxsig_waitinfo(), nxsig_timedwait(), and nxsig_nanosleep(). sched/signal: Add nxsig_nanosleep(). This is an internal OS version of nanosleep(). It differs in that it does not set the errno varaiable and does not create a cancellation point. sched/signal: Add nxsig_timedwait() and nxsig_waitinfo(). These are internal OS versions of sigtimedwait() and sigwaitinfo(). They differ in that they do not set the errno varaiable and they do not create cancellation points.		2017-10-06 08:28:20 -06:00
