Date: Mon, 5 Feb 2001 19:50:44 -0500 (EST) <<On Mon, 5 Feb 2001 15:58:41 -0800 (PST), ikqumei@computer.org said: > ofbuf = (char*)mmap(NULL, ofsz, PROT_READ|PROT_WRITE, /*MAP_DENYWRITE*/MAP_PRIVATE, hOldFile, 0); You have specified a private memory mapping. Modifications made to such mappings are *never* visible anywhere outside that mapping. Use MAP_SHARED to create a mapping which modifies globally-visible state. -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
