# Sanitizer_LaunchData

struct Sanitizer_LaunchData

  Data passed into a launch callback function.

  Data passed into a launch callback function as the `cbdata` argument to Sanitizer_CallbackFunc. The `cbdata` will be this type for `domain` equal to SANITIZER_CB_DOMAIN_LAUNCH. The callback data is only valid 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 it.
