Data Queue APIs
Data queues are a type of system object that you can create, to which one high-level language (HLL) program can send data, and from which another HLL program can receive data. The receiving program can be waiting for the data, or can receive the data later.
Before using a data queue, you must first create it using the Create Data Queue (CRTDTAQ) command.
For additional information, see Using Data Queue APIs.
The data queue APIs are:
- Change Data Queue (QMHQCDQ) changes some attributes of a data queue.
- Clear Data Queue (QCLRDTAQ) clears all entries from a data queue.
- Receive Data Queue (QRCVDTAQ) receives data from the specified data queue.
- Retrieve Data Queue Description (QMHQRDQD) retrieves information about a data queue.
- Retrieve Data Queue Message (QMHRDQM) retrieves an entry from a data queue without removing the entry.
- Send Data Queue (QSNDDTAQ) sends data to the specified data queue.
