This file implements macros for machine independent short and

SIVALS(buf,pos,val) - signed version of SIVAL()
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

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 :-)
