readHandDev
, and writeHandDev
are classes the implement
seqdev
, using OS/2 HFILE handles to actually do the IO.
When these classes are "mixed in" to seqbuf
it results in
working streambuf
. The classes readHandBuf
, writeHandBuf
,
and rwHandBuf
are examples of this. These classes are used in the
implementation of the upipestream classes.
