file:open with O_EXCL mode
Wed Jan 20 12:50:08 CET 2010
I have a problem creating unique files on linux in Erlang.
In current version I cannot be sure that file I am creating is really
unique because even if I check it's existense with filelib:is_regular
and call file:open(..., [write,...]) some other process (not only from
withing Erlang) can create file with the same name. What I need is
atomically create file if it does not exist or get error if it exists.
I found old mail with workaround:
This solution works fine but I'd like not to spawn external commands.
So, is there any way to open file with O_EXCL mode from Erlang? Or will
it be possible in next releases?
