From: Andrea Bolognani Date: Mon, 4 Dec 2017 15:22:02 +0000 (+0100) Subject: util: gettid() is Linux-specific X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=77117e18b703534c43e4e78caf060d7b06653ed8;p=libvirt.git util: gettid() is Linux-specific The manual page clearly states that gettid() is Linux-specific and should not be used in programs that are intended to be portable. Unfortunately, it looks like macOS implemented the functionality and defined SYS_gettid accordingly, only to deprecate syscall() altogether with 10.12 (Sierra), released last late year. To avoid compilation errors, call gettid() on Linux only. Signed-off-by: Andrea Bolognani Reviewed-by: Daniel P.
