I already found this link. Thanks in any case. I want to O_CREATE a file, i.e. do a openFd creating a new file. O_CREATE should be the FileMode, but I don't see in the link below.

Values of type FileMode are defined in System.Posix.Files

See http://haskell.org/ghc/docs/latest/html/libraries/unix/System-Posix-Files.html#1
for the defintions.
