The OpenACC activity API part uses a CUpti_ActivityOpenAcc as a generic representation for any OpenACC activity. The 'kind' field is used to determine the specific activity kind, and from that the CUpti_ActivityOpenAcc object can be cast to the specific OpenACC activity record type appropriate for that kind.

Note that all OpenACC activity record types are padded and aligned to ensure that each member of the record is naturally aligned.

### 6.96. CUpti_CallbackData Struct Reference

### [CUPTI Callback API]

Data passed into a runtime or driver API callback function as the `cbdata` argument to CUpti_CallbackFunc. The `cbdata` will be this type for `domain` equal to CUPTI_CB_DOMAIN_DRIVER_API or CUPTI_CB_DOMAIN_RUNTIME_API. The callback data is valid only within the invocation of the callback function that is passed the data. If you need to retain some data for use outside of the callback, you must make a copy of that data. For example, if you make a shallow copy of CUpti_CallbackData within a callback, you cannot dereference `functionParams` outside of that callback to access the function parameters. `functionName` is an exception: the string pointed to by `functionName` is a global constant and so may be accessed outside of the callback.

### 6.140. NV::Cupti::Checkpoint::CUpti_Checkpoint Struct Reference

### [CUPTI Checkpoint API]

A CUptiCheckpoint object should be initialized with desired options prior to passing into any CUPTI Checkpoint API function. The first call into a Checkpoint API function will initialize internal state based on these options. Subsequent changes to these options will not have any effect.

Checkpoint data is saved in device, host, and filesystem space. There are options to reserve memory at each level (device, host, filesystem) which are intended to allow a guarantee that a certain amount of memory will remain free for use after the checkpoint is saved. Note, however, that falling back to slower levels of memory (host, and then filesystem) to save the checkpoint will result in performance degradation. Currently, the filesystem limitation is not implemented. Note that falling back to filesystem storage may significantly impact the performance for saving and restoring a checkpoint.
