timeout


])

Static method; call it with the package name like new . read , write , and error are either undef or IO::Select objects. The optional argument timeout has the same effect as for the core select call.

Returns an array of three elements, each a reference to an array, or an empty array on error. The arrays hold the handles that are ready for reading, ready for writing, and have error conditions, respectively.
