Hi All,
I am unable to find the equivalent of the atomic_read() call in linux,
most nic driver implementations that i am seeing in opensolaris seem to declare
a uint32_t and then do atomic_add_32 and atomic_sub() seems to be implemented
as atomic_add_32( b ,-a) , while the add/sub operations might work fine , im
not sure if my atomic_read() which im just reading as is #define atomic_read(a)
(*(a) ) would suffice?
Thanks
Som
And forgot to mention that these atomic operations are expensive. The
man page should talk about the cost of these operations.
