While porting to Cygwin the Linux application "sipd" (http://www.sxdesign.com/index.php?page=developer&submnu=sipd ), which uses pthreads, I noticed that socket() calls issued concurrently by several threads often failed, with strerror(errno) saying "operation not permitted". Once I protected all the calls with mutex locks, such errors went away. Is Cygwin's implementation of socket() known to be thread-unsafe?
Enzo P.S. I have written an implementation of the missing gethostbyname_r(), based on a mutex-protected call to gethostbyname(). If useful, I may gladly contribute the code. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
