Building up an MQSeries API in C:

- the API receive information from the application and specially the Put options for example coded in a special field
- some of these options are not allowed for the application

question: among all the options coded (values are added) in that field how can the API identify the values not allowed? - remind us that the fields in which the options are coded is MQLONG type ???

thanks for help.

The different put options correspond to specific positions of bits in the MQLONG. Adding them is equivalent to a logical "OR" operation on the bits positions. Look in the MQ Series header files, you will see that the MQPMO_* values are powers of 2.

In the API implementation, you can easily test which option has been selected. Example:
if (mqpmo & MQPMO_SYNCPOINT)
{
// the MQPMO_SYNCPOINT option has been selected
}


Est-ce que cela répond à votre question?
