Is there a way to do a select() on a named pipe in win32? I want to have it block on the ReadFile call, but for only a few seconds, then if no data was received do some other work.

A traditional pipe is “unnamed” and lasts only as long as the process. A named pipe, however, can last as long as the system is up, beyond the life of the process. It can be deleted if no longer used. Usually a named pipe appears as a file and generally processes attach to it for inter-process communication.
An unnamed pipe is a direct connection between two commands running in the same terminal. If we want to send output from a command in one terminal to another command in a different terminal, we can use a named pipe, or FIFO. FIFO stands for first in, first out. This is a pipe that exists in the file system.
A named pipe is a named, one-way or duplex pipe for communication between the pipe server and one or more pipe clients. All instances of a named pipe share the same pipe name, but each instance has its own buffers and handles, and provides a separate conduit for client/server communication.
You cannot use select() on a named pipe in win32. For emulating select like functionality for named pipes, you can use the named pipe APIs using the overlapped I/O model and WaitForMultipleObjects().
