Modules Returns ‣ CUPTI_SUCCESS ‣ CUPTI_ERROR_NOT_INITIALIZED ‣ CUPTI_ERROR_INVALID_PARAMETER ‣ if valueSize or value is NULL, or if attr is not an activity attribute CUPTI_ERROR_PARAMETER_SIZE_NOT_SUFFICIENT Indicates that the value buffer is too small to hold the attribute value. Description Read an activity API attribute and return it in *value. CUptiResult cuptiActivityGetNextRecord (uint8_t *buffer, size_t validBufferSizeBytes, CUpti_Activity **record) Iterate over the activity records in a buffer. Parameters buffer The buffer containing activity records validBufferSizeBytes The number of valid bytes in the buffer. record Inputs the previous record returned by cuptiActivityGetNextRecord and returns the next activity record from the buffer. If input value is NULL, returns the first activity record in the buffer. Records of kind CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL may contain invalid (0) timestamps, indicating that no timing information could be collected for lack of device memory. Returns ‣ CUPTI_SUCCESS ‣ CUPTI_ERROR_NOT_INITIALIZED ‣ CUPTI_ERROR_MAX_LIMIT_REACHED ‣ if no more records in the buffer CUPTI_ERROR_INVALID_PARAMETER if buffer is NULL. www.nvidia.com CUPTI DA-05679-001 _v5.5 | 46
