Inter-User Communications Vehicle (IUCV) Functions

Message Queues

When an IUCV interrupt occurs, the library places the IUCV external interrupt data on a pending interrupt data queue until it is possible to raise the SIGIUCV signal. Refer to the section "Discovering Asynchronous Signals" in Chapter 5 of SAS/C Library Reference, Volume 1. There is no limit on the number of interrupts that can be placed on the queue.
