Extension of Poll and Select

Extension of Poll and Select

Under IRIX, the poll() system function is not limited to testing STREAMS, but can be applied to file descriptors of all types (see the poll(2) and select(2) reference pages). In addition the select() function can be applied to STREAMS file descriptors. You may want to note this under the heading "STREAMS System Calls" in Chapter 2 of STREAMS Modules and Drivers, UNIX SVR4.2.
