OS2::PrfDB and OS2::PrfDB::Sub. First one supports one argument, the name of the file to open, the second
one the name of the file to open and so called Application name, or the primary key of the database.

One may substitute a handle for already opened ini-file instead of the file
name (obtained via low-level access functions). In particular, 3 functions
SystemIni, UserIni, and AnyIni
provide handles to the ``systemish'' databases. AniIni will read from both,
and write into User database.
OS2::Prf. They are
appname key. If key is undef, return the ``\0'' delimited list of keys, terminated by \0. If appname is undef, returns the list of possible appnames in the same form.
value is not defined, removes the key. If the key is not defined, removes the appname.
val is 1, it is User database, if 2, System database, if 0, handle for ``both'' of them: the handle works for read from
any one, and for write into User one.
tie interface, one may use the following functions
from the package OS2::Prf::Hini:
