C example: Disconnecting from a queue manager

This example demonstrates how to use the MQDISC call to disconnect a program from a queue manager in z/OS® batch.

The variables used in this code extract are those that were set in C example: Connecting to a queue manager. This extract is taken from the Browse sample application (program CSQ4BCA1).

For the names and locations of the sample applications, see Using the sample procedural programs for z/OS.
