Typedef
typedef [type] test_pal_thread_return_t;
Optionality
This typedef is mandatory.
Notes
When a thread function returns, it returns a value to the OS. This typedef is the type of than return value.
If we look at the Windows thread function prototype;
DWORD WINAPI ThreadProc( _In_ LPVOID lpParameter );
We see the return type is DWORD.
(The WINAPI part is actually a compiler directive and is handled in the abstraction layer by the TEST_PAL_CALLING_CONVENTION define.)
Example
typedef DWORD test_pal_thread_state_t;
