I want use “BYTE_ORDER” macro in my Xcode project but i can’t because i don’t know in which header it’s defined.
When I look in my Xcode 4.3.X installation, I find the “
byte_order.h” file located in a few places:You’d probably want to do a “
#include <architecture/byte_order.h>” in your .c file in order to pick up the byte_order macros.For the actual “
BYTE_ORDER” define itself, well that’s defined in a few specific places but the way it’s defined seems meant for very specific purposes. For example, this define:is meant only for Kernel Extensions (drivers).
And this define:
is meant for X11 stuff (ewww).
I’d say the best thing to do is use the “
NXHostByteOrder” inline function in the “byte_order.h” file, and this will give you the byte order of the current host.
