Unhappy checking/queueing access to file in tcl ?

hi, i started using a sql .dll in itcl for queueing access to the stats log file in a zipscript, but this is slow and mechanical (and now i got a new bug with it :X).

is there some trick to checking the status of a file with another tcl instance of zipscript, ie.

zs_1 has.ioftpd.log 'open' (thus i would read this as 'locked').
zs_2 checks 'status' of .ioftpd.log, if opened by another script ('locked'), queue.
zs_1 'closed' ('unlocked') .ioftpd.log
zs_2 'opens' .ioftpd.log (thus 'locking' it somehow).

?

any help, thx.

If you want to lock "testfile", try and create a *new* "testfile.lock" in the same directory. Repeat (with ample sleep) until this succeeds. To unlock, simply remove the file. This method is supported by almost all configurations.

flock might be avail too

ok, then to queue ? maybe, after ms ?script script script ...?

in a loop, ? say, ?

while {1} {
after 1000
set a [file exists "c:/blah.log"]
if {0 == $a} {
break
}
}

hmm, that should do it. what about thread safe stuff ?
