Hi,=20
I have the following structure which needs to be locked, so that no oth=
er users in the website can change it, other than the current user-himsel=
f.
=20
parent1
|
|----> child1
|
|----> child2
|
|----> child3

=20
child1, child2 and child3 needs to be locked only when parent1 is locke=
d.
There are no grand-child nodes. How can I achieve this in perl???

Do you mean this is a directory structure on the filesystem? If so, what filesystem are you working on? Also, by what means are "other users" able to
"modify" this structure? Is it users logging in to the server or users running the same script from a website which in turn is accessing the
"structure" you describe? I.e. several users are accessing/modifying the "structure" via a cgi script but you don't want several users being able to
modify the "structure" in case changes are lost?

A few more details would be helpful.
