问题 Assuming I have opened dev/poll as mDevPoll , is it safe for me to call code like this struct pollfd tmp_pfd; tmp_pfd.fd = fd; tmp_pfd.events = POLLIN; // Write pollfd to /dev/poll write(mDevPoll, &tmp_pfd, sizeof(struct pollfd)); ...simultaneously from multiple threads, or do I need to add my own synchronisation primitive around mDevPoll ? 回答1: Solaris 10 claims to be POSIX compliant. The write() function is not among the handful of system interfaces that POSIX permits to be non-thread-safe,

问题 I realize that I can’t reliably count on ps | grep or variants to accurately tell me what PID is started. However I know what I need for interim until this problem is resolved in the next release. I have a process named Foo that is the parent, TEST1 and TEST2 are the child processes. If TEST1 and/or TEST2 dies off Foo will continue to run and will not respawn TEST1 and/or TEST2 which is needed to function properly. How do I know this because the program to restart TEST1 and/or TEST2 requires

问题 Solaris 11 has wget command, like Linux's. Is there wget or wget like command for Solaris 10? 回答1: The wget command in Solaris 10 is somewhat hidden from sight. You can find it here /usr/sfw/bin/wget This was checked on s10u10 回答2: My Solaris system has it installed, but I do not control the image we use to install it. I see this: $ which wget /usr/sfw/bin/wget $ wget --version GNU Wget 1.12 built on solaris2.10. $ pkginfo -l SUNWwgetr PKGINST: SUNWwgetr NAME: GNU wget - utility to retrieve

How to tell CPAN about path to make and cc

由 二次信任 提交于 2019-12-04 04:57:05
Running Perl 5.10 CPAN on Solaris with opencsw.org packages, Makefile.PL from packages can't find the correct path and cc (gcc). I found the path to make and set it to gmake, but I can't find any setting for cc. I thought I once set this in CPAN/Config.pm (or with o config ...) but can no longer find any setting and don't have enough patience to wade through the thicket to figure out where such a basic thing gets set. Does anyone know? cpan doesn't need to know where gcc or equivalent is, because it isn't cpan 's job to call it directly. Usually it's Makefile.PL or Build.PL that needs to know
