+   This file implements macros for machine independent short and
+   int manipulation
+
+Here is a description of this file that I emailed to the samba list once:
+
+> I am confused about the way that byteorder.h works in Samba. I have

+
+sure.
+
+Ok, now to the macros themselves. I'll take a simple example, say we
+want to extract a 2 byte integer from a SMB packet and put it into a
+type called uint16_t that is in the local machines byte order, and you
+want to do it with only the assumption that uint16_t is _at_least_ 16
+bits long (this last condition is very important for architectures
+that don't have any int types that are 2 bytes long)
+
+You do this:
+
+#define CVAL(buf,pos) (((uint8_t *)(buf))[pos])
+#define PVAL(buf,pos) ((unsigned int)CVAL(buf,pos))
+#define SVAL(buf,pos) (PVAL(buf,pos)|PVAL(buf,(pos)+1)<<8)
+
+then to extract a uint16_t value at offset 25 in a buffer you do this:
+
+char *buffer = foo_bar();
+uint16_t xx = SVAL(buffer,25);
+
+We are using the byteorder independence of the ANSI C bitshifts to do
+the work. A good optimising compiler should turn this into efficient
+code, especially if it happens to have the right byteorder :-)
+
+I know these macros can be made a bit tidier by removing some of the
+casts, but you need to look at byteorder.h as a whole to see the
+reasoning behind them. byteorder.h defines the following macros:
+
+SVAL(buf,pos) - extract a 2 byte SMB value
+IVAL(buf,pos) - extract a 4 byte SMB value
+BVAL(buf,pos) - extract a 8 byte SMB value
+SVALS(buf,pos) - signed version of SVAL()
+IVALS(buf,pos) - signed version of IVAL()
+BVALS(buf,pos) - signed version of BVAL()
+
+SSVAL(buf,pos,val) - put a 2 byte SMB value into a buffer
+SIVAL(buf,pos,val) - put a 4 byte SMB value into a buffer
+SBVAL(buf,pos,val) - put a 8 byte SMB value into a buffer
+SSVALS(buf,pos,val) - signed version of SSVAL()
+SIVALS(buf,pos,val) - signed version of SIVAL()
+SBVALS(buf,pos,val) - signed version of SBVAL()
+
+RSVAL(buf,pos) - like SVAL() but for NMB byte ordering
+RSVALS(buf,pos) - like SVALS() but for NMB byte ordering
+RIVAL(buf,pos) - like IVAL() but for NMB byte ordering
+RIVALS(buf,pos) - like IVALS() but for NMB byte ordering
+RSSVAL(buf,pos,val) - like SSVAL() but for NMB ordering
+RSIVAL(buf,pos,val) - like SIVAL() but for NMB ordering
+RSIVALS(buf,pos,val) - like SIVALS() but for NMB ordering
+
+it also defines lots of intermediate macros, just ignore those :-)
