Member Data Documentation

◆ address

item::GenericPointerValue clues::SetTIDAddressSystemCall::address

location where to find a futex the kernel operates on.

When the calling thread exits and other threads exist in the process then this address will be manipulated with futex operations.

Definition at line 32 of file thread.hxx.

◆ caller_tid

item::ThreadIDItem clues::SetTIDAddressSystemCall::caller_tid

This will always be the TID of the caller.

Definition at line 35 of file thread.hxx.
