Subject Re: file locking log files ?
Date Mon, 28 Apr 2003 20:13:12 GMT
Files open for APPEND, write on unix should write atomically to the file.
On Win32 in apr/file_io for Apache2 we set up our own locking to do the
same sort of thing.  As far as cross-machine locking, I dunno, but this
has historically been sufficient for one machine/cross-process log files.

the Apache logging API provided file locking so that I do not have to worry about it.
