| /* |
| * XDR provides a conventional way for converting between C data |
| * types and an external bit-string representation. Library supplied |
| * routines provide for the conversion on built-in C data types. These |
| * routines and utility routines defined here are used to help implement |
| * a type encode/decode routine for each user-defined type. |
| * |
| * Each data type provides a single procedure which takes two arguments: |
| * |
| * bool_t |
| * xdrproc(xdrs, argresp) |
| * XDR *xdrs; |
| * <type> *argresp; |
| * |
| * xdrs is an instance of a XDR handle, to which or from which the data |
| * type is to be converted. argresp is a pointer to the structure to be |
| * converted. The XDR handle contains an operation field which indicates |
| * which of the operations (ENCODE, DECODE * or FREE) is to be performed. |
| * |
| * XDR_DECODE may allocate space if the pointer argresp is null. This |
| * data can be freed with the XDR_FREE operation. |
| * |
| * We write only one procedure per data type to make it easy |
| * to keep the encode and decode procedures for a data type consistent. |
| * In many cases the same code performs all operations on a user defined type, |
| * because all the hard work is done in the component type routines. |
| * decode as a series of calls on the nested data types. |
