Sanitization is controlled by a SanitizationInformation struct to be read from the client's memory. The address of this struct is either passed in a ClientInformation when the client requests a crash dump, or as a flag to the handler --sanitization_information.

|
||
//! not confuse this with module-level annotations, which are under the
|
||
//! control of the crashing process, and are used to implement Chrome’s

//! “crash keys.” Process-level annotations are those that are beyond the
|
||
//! control of the crashing process, which must reliably be set even if
|
||
//! the process crashes before it’s able to establish its own annotations.
|
||
//! To interoperate with Breakpad servers, the recommended practice is to
|
||
//! specify values for the `"prod"` and `"ver"` keys as process
|

//! annotations.

//! \param[in] user_stream_data_sources Data sources to be used to extend
|
||
//! crash reports. For each crash report that is written, the data sources
|
||
//! are called in turn. These data sources may contribute additional
|
||
//! minidump streams. `nullptr` if not required.
