That's one perfectly legitimate way of doing it, yes. However, the real issue here is not system calls, it's the binary interface to libc. If the third-party library binds to anything other than a clearly defined interface layer in the application, ie. it makes any calls at all into libc, the chances are good that it will fail because the interface to libc is defined at the source level, not the binary level. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the messagehome | help
