78 * Copyright (C) 1984, Sun Microsystems, Inc.
82 * XDR provides a conventional way for converting between C data
83 * types and an external bit-string representation. Library supplied
84 * routines provide for the conversion on built-in C data types. These
85 * routines and utility routines defined here are used to help implement
86 * a type encode/decode routine for each user-defined type.
88 * Each data type provides a single procedure which takes two arguments:
91 * xdrproc(xdrs, argresp)
95 * xdrs is an instance of a XDR handle, to which or from which the data
96 * type is to be converted. argresp is a pointer to the structure to be
97 * converted. The XDR handle contains an operation field which indicates
98 * which of the operations (ENCODE, DECODE * or FREE) is to be performed.
100 * XDR_DECODE may allocate space if the pointer argresp is null. This
101 * data can be freed with the XDR_FREE operation.
103 * We write only one procedure per data type to make it easy
104 * to keep the encode and decode procedures for a data type consistent.
105 * In many cases the same code performs all operations on a user defined type,
106 * because all the hard work is done in the component type routines.
107 * decode as a series of calls on the nested data types.
111 * Xdr operations. XDR_ENCODE causes the type to be encoded into the
112 * stream. XDR_DECODE causes the type to be extracted from the stream.
113 * XDR_FREE can be used to release the space allocated by an XDR_DECODE
123 * This is the number of bytes per unit of external data.
125 #define BYTES_PER_XDR_UNIT (4)
128 * A xdrproc_t exists for each data type which is to be encoded or decoded.
130 * The second argument to the xdrproc_t is a pointer to an opaque pointer.
131 * The opaque pointer generally points to a structure of the data type
132 * to be decoded. If this pointer is 0, then the type routines should
133 * allocate dynamic storage of the appropriate size and return it.
