I've got getcontext, setcontext, makecontext, and swapcontext implemented and would like to add them to libc. I've made the patch available at: http://people.freebsd.org/~deischen/ucontext/uc-libc-sys.diffs These are library level versions of these functions. Solaris has getcontext and setcontext as system calls. My intent is to replace libc_r's use of setjmp/longjmp and jmp_buf munging with these functions, so I don't want them as system calls. I also want to use them with the KSE-enabled threads library. Is there a reason that getcontext and setcontext need to be system calls? For those not familiar with these functions, see: http://www.opengroup.org/onlinepubs/007908799/xsh/ucontext.h.html -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
