From: Kevin Day Date: Sun, 11 Apr 2021 04:57:05 +0000 (-0500) Subject: Update: Finish implementing the thread condition functions. X-Git-Tag: 0.5.3~61 X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=96540858a5dd0fa974ea67ead14ac0263b5a2c89;p=fll Update: Finish implementing the thread condition functions. It looks like the f_thread_condition_wait() f_thread_condition_wait_timed() functions were not fully written. Add missing handlers. The f_thread_condition_wait_timed() was even missing the return case of F_time! Update the comments as the "time" value is relative to the absolute system clock time. Add F_dead, F_live, and related. --- diff --git a/level_0/f_status/c/status.h b/level_0/f_status/c/status.h index f1e47a8..a3e2745 100644 --- a/level_0/f_status/c/status.h +++ b/level_0/f_status/c/status.h @@ -169,6 +169,8 @@ extern "C" { F_control_group_not, F_critical, F_critical_not, + F_dead, + F_dead_not, F_deadlock, F_deadlock_not, F_descriptor, @@ -218,6 +220,8 @@ extern "C" { F_limit_not, F_link, F_link_not, + F_live, + F_live_not, F_lock, F_lock_not, F_loop, diff --git a/level_0/f_thread/c/thread.c b/level_0/f_thread/c/thread.c index 3b553cc..be58bd8 100644 --- a/level_0/f_thread/c/thread.c +++ b/level_0/f_thread/c/thread.c @@ -1183,6 +1183,8 @@ extern "C" { if (error) { if (error == EINVAL) return F_status_set_error(F_parameter);
