Aaron, Not that I've done that much with the IFS, but the way I read the manuals/Redbooks, if you want an exclusive lock, you need to add x'10' (exclusive use) to openflags to get the behavior you want. ... D O_EXCL C x'10' ... handle = open('/tmp/Example3.xml': (O_RDWR + O_EXCL)); ... I don't set the open flag parameter the same way you do, but I think this will give you the idea. HTH, Roger -----Original Message----- From: Bartell, Aaron L. (TC) [mailto:ALBartell@xxxxxxxxxxxxxx] Sent: Friday, August 29, 2003 14:32 To: 'RPG400-L@xxxxxxxxxxxx' Subject: IFS file in use I am trying to lock an IFS file by opening it in one program (in debug) and then seeing if I can open it in another program (in debug in separate session). I thought the second program should puke and not provide me a handle for the file, but it gives me the handle just fine. I am assuming that since I am opening it for reading and writing that I should get a file lock but evidently not. Here is the program I am using to test the process: H DFTACTGRP(*NO) D open PR 10I 0 ExtProc('open') D filename * value options(*string) D openflags 10I 0 value D mode 10U 0 value options(*nopass) D codepage 10U 0 value options(*nopass) D close PR 10I 0 ExtProc('close') D handle 10I 0 value D* Reading & Writing D O_RDWR C 4 D handle S 10I 0 D rc S 10I 0 /Free handle = open('/tmp/Example3.xml': O_RDWR); rc = close(handle); *InLR = *On; /End-Free Any ideas?
