51 * XDR provides a conventional way for converting between C data
52 * types and an external bit-string representation. Library supplied
53 * routines provide for the conversion on built-in C data types. These
54 * routines and utility routines defined here are used to help implement
55 * a type encode/decode routine for each user-defined type.
57 * Each data type provides a single procedure which takes two arguments:
60 * xdrproc(xdrs, argresp)
64 * xdrs is an instance of a XDR handle, to which or from which the data
65 * type is to be converted. argresp is a pointer to the structure to be
66 * converted. The XDR handle contains an operation field which indicates
67 * which of the operations (ENCODE, DECODE * or FREE) is to be performed.
69 * XDR_DECODE may allocate space if the pointer argresp is null. This
70 * data can be freed with the XDR_FREE operation.
72 * We write only one procedure per data type to make it easy
73 * to keep the encode and decode procedures for a data type consistent.
74 * In many cases the same code performs all operations on a user defined type,
75 * because all the hard work is done in the component type routines.
76 * decode as a series of calls on the nested data types.
80 * Xdr operations. XDR_ENCODE causes the type to be encoded into the
81 * stream. XDR_DECODE causes the type to be extracted from the stream.
82 * XDR_FREE can be used to release the space allocated by an XDR_DECODE
92 * This is the number of bytes per unit of external data.

100 * Contains operation which is being applied to the stream,
101 * an operations vector for the paticular implementation (e.g. see xdr_mem.c),
