Websphere MQ Everyplace for Native Platforms Types

Types

In addition to the MQe items and their associated handles there are also the MQe types. These, like the handles, enable the end user to write platform independent code, and should be used throughout an application using the Websphere MQ Everyplace API. These types will be consistent across different platforms within the Websphere MQ Everyplace family. The types provided are:

MQEUINT64      Unsigned 64 bit integer
MQEINT64       Signed 64 bit integer
MQEUINT32      Unsigned 32 bit integer   
MQEINT32       Signed 32 bit integer
MQEUINT16      Unsigned 16 bit integer                        
MQEINT16       Signed 16 bit integer
MQEUINT8       Unsigned 8 bit integer 
MQEINT8        Signed 8 bit integer    
MQEBOOL        Boolean Enumeration - takes values MQE_TRUE and MQE_FALSE.  
MQEBYTE        1 byte char data type
MQECHAR        1 byte unsigned char data type
MQECHAR16      2 byte unsigned char data type
MQECHAR32      4 byte unsigned char data type
MQEFLOAT       IEEE 754 Floating Point 32 bits
MQEDOUBLE      IEEE 754 Floating Point 64 bits 
MQEVOID        Void datatype 
MQEHANDLE      Generic Handle datatype  

Although there are numerous items and types within Websphere MQ Everyplace, with just a few of them it is possible to use most of the APIs required to administer Websphere MQ Everyplace, create a queue manager, queues and connection definitions and to then put and get messages.

Note that MQE_TRUE is defined to be 1. Therefore, testing flag==MQE_TRUE will not be guaranteed to evaluate to true if flag evaluates to any other (usually valid "true") value, such as 2.
