.TH Wy_FdSet 3wy "libwy v0.31"
.SH NAME
Wy_FdSet \- set of file descriptor
.SH SYNOPSIS
.B #include <wyselect.h>
.PP
Wy_FdSet is a discardable class for ::fd_set denoting set of file descriptors.
At most one identical file descriptor is contained.

Note: Wy_FdSet object have to be reset before each call of Wy::select
