/*
* 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.
*/
/*
* Xdr operations. XDR_ENCODE causes the type to be encoded into the
* stream. XDR_DECODE causes the type to be extracted from the stream.
* XDR_FREE can be used to release the space allocated by an XDR_DECODE
