### 5.90. 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.

  The activity record correlation ID for this callback. For a driver domain callback (i.e. `domain` CUPTI_CB_DOMAIN_DRIVER_API) this ID will equal the correlation ID in the CUpti_ActivityAPI record corresponding to the CUDA driver function call. For a runtime domain callback (i.e. `domain` CUPTI_CB_DOMAIN_RUNTIME_API) this ID will equal the correlation ID in the CUpti_ActivityAPI record corresponding to the CUDA runtime function call. Within the callback, this ID can be recorded to correlate user data with the activity record. This field is new in 4.1.

#### Variables

CUcontext CUpti_ResourceData::context [inherited]

  For CUPTI_CBID_RESOURCE_CONTEXT_CREATED and CUPTI_CBID_RESOURCE_CONTEXT_DESTROY_STARTING, the context being created or destroyed. For CUPTI_CBID_RESOURCE_STREAM_CREATED and CUPTI_CBID_RESOURCE_STREAM_DESTROY_STARTING, the context containing the stream being created or destroyed.

void * CUpti_ResourceData::resourceDescriptor [inherited]

  Reserved for future use.

CUstream CUpti_ResourceData::stream [inherited]

  For CUPTI_CBID_RESOURCE_STREAM_CREATED and CUPTI_CBID_RESOURCE_STREAM_DESTROY_STARTING, the stream being created or destroyed.

### 5.131. CUpti_SynchronizeData Struct Reference

### [CUPTI Callback API]

Data passed into a synchronize callback function as the `cbdata` argument to CUpti_CallbackFunc. The `cbdata` will be this type for `domain` equal to CUPTI_CB_DOMAIN_SYNCHRONIZE. 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.

#### Public Variables

CUcontext context
CUstream stream

#### Variables

CUcontext CUpti_SynchronizeData::context [inherited]

  The context of the stream being synchronized.

CUstream CUpti_SynchronizeData::stream [inherited]

  The stream being synchronized.

### 5.132. Header Struct Reference

### [CUPTI PC Sampling Utility API]

#### Public Variables

uint32_t totalBuffers
uint32_t version

#### Variables

uint32_t Header::totalBuffers [inherited]

  Total number of buffers present in the file.

uint32_t Header::version [inherited]

  Version of file format.

### 5.133. 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.
