* Now for the macros that do the simple stuff and call the functions |
| 70 |
* for the hard stuff. |
| 71 |
* These macros use several vars. declared in rpcm_reqhead and these |
| 72 |
* vars. must not be used elsewhere unless you are careful not to corrupt |
| 73 |
* them. The vars. starting with pN and tN (N=1,2,3,..) are temporaries |
| 74 |
* that may be used so long as the value is not expected to retained |
| 75 |
* after a macro. |
| 76 |
* I know, this is kind of dorkey, but it makes the actual op functions |
| 77 |
* fairly clean and deals with the mess caused by the xdr discriminating |
| 78 |
* unions. |
