Dear Linux Programmers,

I am using fedora 10 with version of 2.6.27.5-117.fc10.x86_64 #1 SMP.
I am looking for the system head file where memory barrier functions
are declared.

Thanks,

dbtouch

There is no memory barrier API provided by default. If you want one,
you have to code it. On x86-64, this is sufficient:

#define membar() __asm__ __volatile__("" : : : "memory")
