You might be able to pull such info out of /proc or whatever your OS-equivalent might be, but it's undoubtably easier to system or exec an external binary like fstat (BSD), fuser (Solaris), lsof (generic Unicies) ... I'm sure similar tools exist for other OSes.

    --k.

redhat , mandrake, and debian linux distros as well as solairs and probbably other Unices include fuser, which is my tool of choice for obtaining this info, from the man page : 'fuser displays the PIDs of processes using the specified files or file systems. In the default display mode, each file name is followed by a letter denoting the type of access' -Tom

See also http://www.sysinternals.com for a win32 utility that can do things like that, I think. (I've never played much with a multiuser win32 system.)
