From: Ronan Desplanques <[email protected]>
This patches fixes the signature of the binding to SetThreadAffinityMask
in the run-time library. It also fixes the error checking after calls
to SetThreadAffinityMask. The previous code behaved as if
SetThreadAffinityMask returned 1 on success, but it in fact returns a
pointer value on success and 0 on failure.
gcc/ada/
* libgnarl/s-taprop__mingw.adb (Set_Task_Affinity): Fix usage of
SetThreadAffinityMask.
* libgnat/s-winext.ads (SetThreadAffinityMask): Fix binding
signature.
Tested on x86_64-pc-linux-gnu, committed on master.
