Thanks for the help. Doesn't look like the code in libc_r using mmap. It uses pthread. I need a mmap coded sem/shm implementation to port a software from UNIX to NT. NT has no sysv sem/shm nor pthread. There's a Linux sysv lib but it's GNU, look like I have to write my own sysv IPC for NT. Well, any more pointers? -------------------------------------------------- WWW.XGFORCE.COM - The Next Generation Server Clustering and Enterprise Firewall/VPN Solutions. -------------------------------------------------- ----- Original Message ----- From: "Kip Macy" <kmacy@netapp.com> To: "Matthew" <matthew@netsol.net> Cc: <questions@FreeBSD.ORG> Sent: Tuesday, February 12, 2002 4:07 PM Subject: Re: sysv semaphore > This is really a questions for -questions so I'm moving it to that list. > The semaphore code is all tied to libc_r pthreads, and can be found in the > corresponding directory under libc_r, so I din't know if that fits > your needs.
