71 * Now for the macros that do the simple stuff and call the functions
73 * These macros use several vars. declared in rpcm_reqhead and these
74 * vars. must not be used elsewhere unless you are careful not to corrupt
75 * them. The vars. starting with pN and tN (N=1,2,3,..) are temporaries
76 * that may be used so long as the value is not expected to retained
78 * I know, this is kind of dorkey, but it makes the actual op functions
79 * fairly clean and deals with the mess caused by the xdr discriminating
