Subject: [Linux-ia64] atomic add instruction
Date: Tue, 17 Jul 2001 22:09:46 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590693005852@msgid-missing> (raw)
Hello Everyone,
I want an atomic function that does addition of a constant to the value in
a memory location and returns the previous value in that location.
Is there any macro/function defined in IA-64's atomic.h already. (will
fetch-and-add solve the purpose?) or one should write his own function for
it
Thanking in advance,
Swami
