<p>Function type for callback used by CUPTI to return a buffer of activity records. This callback function returns to the CUPTI
client a buffer containing activity records. The buffer contains <tt class="ph tt code">validSize</tt> bytes of activity records which should be read using cuptiActivityGetNextRecord. The number of dropped records can be read
using cuptiActivityGetNumDroppedRecords. After this call CUPTI relinquished ownership of the buffer and will not use it anymore.
The client may return the buffer to CUPTI using the CUpti_BuffersCallbackRequestFunc callback. Note: CUDA 6.0 onwards, all
buffers returned by this callback are global buffers i.e. there is no context/stream specific buffer. User needs to parse
the global buffer to extract the context/stream specific activity records.

<p>The profiling results can be inconsistent in case auto boost is enabled. CUPTI tries to disable auto boost while profiling.
It can fail to disable in cases where user does not have the permissions or CUDA_AUTO_BOOST env variable is set. The function
can be used to query whether auto boost is enabled.
