I'm having difficulty digging up the reference, but I think I recall seeing something that said, roughly, on W32 there are 2 sets of buffers - those in the user level library and those in the kernel level driver, and FlushFileBuffers drains the first, while _commit drains both (it includes a call to FlushFileBuffers).
I'm also fairly sure I saw something like #define fsync _commit in the Berkeley DB sources the other day, which might be a clue. I'll be happy to be corrected, though. cheers andrew ----- Original Message ----- From: "Dann Corbit" <[EMAIL PROTECTED]> To: "PostgreSQL Hackers" <[EMAIL PROTECTED]> Sent: Monday, February 03, 2003 3:15 PM Subject: [HACKERS] Win32 and fsync() > For Win32, in order to emulate fsync() we will need to call > FlushFileBuffers(): > http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/ > base/flushfilebuffers.asp > > ---------------------------(end of broadcast)--------------------------- > TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
