CmtGetTSQReadPtr () usage

[David_Lee]

I'd like to know using CmtGetTSQReadPtr() to read data from a TSQ, after reading, if it will remove the data items from the TSQ at the same time? Because I know when using the CmtReadTSQData() and specify  the OPT_TSQ_READ_PEEK parameter, it will leave the data in the queue.

Hi David,

After calling CmtGetTSQReadPtr, you must also call CmtReleaseTSQReadPtr when you are done with the read pointer. When you call CmtReleaseTSQReadPtr, you must pass a value for the "Items Read" parameter. If you pass 0 for that parameter, all of the data remains in the queue. Based on the documentation, I believe that passing a non-zero value will cause that number of items to be removed from the queue.

I hope this helps.
