The aStatus structure is an optional array that contains error codes returned by Message Queuing.
An aStatus array is included as a member in the following property structures:
MQQUEUEPROPS (queue properties)
MQMSGPROPS (message properties)
MQMGMTPROPS (queue and computer management properties).
MQQMPROPS (queue manager properties).
MQPRIVATEPROPS (private computer properties)
Message Queuing errors are divided into four categories (by increasing order of severity); the category can be determined by looking at the upper two bits of the error code (success = 00, informational = 01, warning = 10, fatal = 11).
