From bc42d96d66d91cbfba98c0cbc34530c1156d6120 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Matu=C5=A1ka?= Date: Thu, 9 May 2024 16:42:51 +0200 Subject: [PATCH] Unbreak FreeBSD cross-build on MacOS broken in 051460b8b MacOS used FreeBSD-compatible getprogname() and pthread_getname_np(). But pthread_getthreadid_np() does not exist on MacOS. This implements libspl_gettid() using pthread_threadid_np() to get the thread id of the current thread.
