Description

A numeric key that identifies the shared memory segment in which the structures used by your application are located. In a single-processor environment, the interprocess communication (IPC) key identifies the bulletin board. In a multiple-processor or LAN environment, this key names the message queue of the Distinguished Bulletin Board Liaison (DBBL).

Valid Values

An integer in the range from 32769 to 262144. If you expect to define a network of machines using TCP/IP addressing, you may find it helpful to express the value of the IPC key in hexadecimal notation.
