◆ GetThreadItemInfo()

AppleGetThreadItemInfoHandler::GetThreadItemInfoReturnInfo AppleGetThreadItemInfoHandler::GetThreadItemInfo ( Thread thread,
lldb::tid_t  thread_id,
lldb::addr_t  page_to_free,
uint64_t  page_to_free_size,
lldb_private::Status error 
)

Get the information about a work item by calling __introspection_dispatch_thread_get_item_info.

If there's a page of memory that needs to be freed, pass in the address and size and it will be freed before getting the list of queues.

Parameters
[in]thread_idThe thread to get the extended backtrace for.
[in]page_to_freeAn address of an inferior process vm page that needs to be deallocated, LLDB_INVALID_ADDRESS if this is not needed.
[in]page_to_free_sizeThe size of the vm page that needs to be deallocated if an address was passed in to page_to_free.
[out]errorThis object will be updated with the error status / error string from any failures encountered.
Returns
The result of the inferior function call execution. If there was a failure of any kind while getting the information, the item_buffer_ptr value will be LLDB_INVALID_ADDRESS.
