# 7.126. CUpti_NvtxData

struct CUpti_NvtxData

  Data passed into a NVTX callback function.

  Data passed into a NVTX callback function as the `cbdata` argument to CUpti_CallbackFunc. The `cbdata` will be this type for `domain` equal to CUPTI_CB_DOMAIN_NVTX. Unless otherwise notes, 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.
