TCL language: how to access ACLs?

How to access Access control list of a file via TCL? e.g. if a
particular file has permission for two users, I want to access these
two users names. So, need to ACLs.

If this is not possible via TCL, which command I can use on windows to
get the ACLs? (e.g. on Linux one can use getacl command)

Thanks,
Narendra

Maybe look at the TWAPI extension. Dunno whether it exposes the exact
API you are after, but if anybody does, it will ;-)

Alternatively, you can use [exec] to spawn an instance of a command-
line ACL tool like cacls:

Example to get this for C:\windows

package require twapi

set sd [twapi::get_resource_security_descriptor file "c:/windows"] ;#
Security descriptor
twapi::get_security_descriptor_text $sd -resourcetype file; # Print
security descriptor
twapi::get_security_descriptor_dacl $sd; # Get the DACL in the
security descriptor

See the twapi documentation for more
