.SH DESCRIPTION
.IX Header "DESCRIPTION"
Conway discourages the use of a raw \f(CWselect()\fR when setting
autoflushes.  We'll extend that further by simply prohibiting the
one-argument form of \f(CWselect()\fR entirely; if you really need it you
should know when/where/why that is.  For performing autoflushes,
Conway recommends the use of \f(CW\*(C`IO::Handle\*(C'\fR instead.
