//! \param[in] client_uid The client's user ID.
//! \param[in] requesting_thread_stack_address An address on the stack of the

//!     address, the exception will be assigned to the thread whose stack
//!     address range contains this address. If 0, \a requesting_thread_id will

//! \param[out] requesting_thread_id The thread ID of the thread corresponding

//!     not be determined. Optional.
//! \param[out] process_snapshot A snapshot of the client process, valid if this

//! \param[out] sanitized_snapshot A sanitized snapshot of the client process,
//!     valid if this function returns `true` and sanitization was requested in
//!     \a info.
//! \return `true` if \a process_snapshot was successfully created. A message
//!     will be logged on failure, but not if the snapshot was skipped because
//!     handling was disabled by CrashpadInfoClientOptions.
