Hi, I've been playing some with getting Mozilla to compile under FreeBSD, and have succeeded (to some extent - it's a moving target). One thing which I would like to do is enable NSPR (the NetScape Portable Runtime) to use poll() under FreeBSD-current. With a few changes to ifdef's I can get it to work. However, when I compile NSPR to use pthreads, then poll is not available and I must use the fake poll() provided in NSPR. The pthreaded version of NSPR requires a poll() call of some form. The CVS logs show that poll() is being hidden in libc_r because a wrapper has not been written... However, this is way out of my league. Does anyone have such a wrapper in their local tree, or is it a hard thing to write? And would looking at the NSPR thread-safe wrapper for poll() help? http://cvs-mirror.mozilla.org/webtools/lxr/source/nsprpub/pr/src/md/unix/uxwrap.c Is there anyone who can help? I'd like to see poll() used in official ELF releases of Netscape in the future, especially if someone makes kernel threads work... Regards, -Jeremy PS: pthread.h prototypes pthread_attr_setinheritsched(), but there is no such function. In NSPR calls to any pthread_*sched* functions are surrounded by _POSIX_THREAD_PRIORITY_SCHEDULING, which is a commented out define in pthreads.h. Maybe the prototypes should be hidden behind this define? At lease it will give a compile error, not a link error... -- | "In this world of temptation, I will stand for what is right. --+-- With a heart of salvation, I will hold up the light. | If I live or if I die, if I laugh or if I cry, | in this world of temptation, I will stand." -Pam Thum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
