112 * xdr.h, External Data Representation Serialization Routines.
114 * Copyright (C) 1984, Sun Microsystems, Inc.
118 * XDR provides a conventional way for converting between C data
119 * types and an external bit-string representation. Library supplied
120 * routines provide for the conversion on built-in C data types. These
121 * routines and utility routines defined here are used to help implement
122 * a type encode/decode routine for each user-defined type.
124 * Each data type provides a single procedure which takes two arguments:
127 * xdrproc(xdrs, argresp)
131 * xdrs is an instance of a XDR handle, to which or from which the data
132 * type is to be converted. argresp is a pointer to the structure to be
133 * converted. The XDR handle contains an operation field which indicates
134 * which of the operations (ENCODE, DECODE * or FREE) is to be performed.
136 * XDR_DECODE may allocate space if the pointer argresp is null. This
137 * data can be freed with the XDR_FREE operation.
139 * We write only one procedure per data type to make it easy
140 * to keep the encode and decode procedures for a data type consistent.
141 * In many cases the same code performs all operations on a user defined type,
142 * because all the hard work is done in the component type routines.
143 * decode as a series of calls on the nested data types.
147 * Xdr operations. XDR_ENCODE causes the type to be encoded into the
148 * stream. XDR_DECODE causes the type to be extracted from the stream.
149 * XDR_FREE can be used to release the space allocated by an XDR_DECODE
159 * This is the number of bytes per unit of external data.
161 #define BYTES_PER_XDR_UNIT (4)
164 * A xdrproc_t exists for each data type which is to be encoded or decoded.
166 * The second argument to the xdrproc_t is a pointer to an opaque pointer.
167 * The opaque pointer generally points to a structure of the data type
168 * to be decoded. If this pointer is 0, then the type routines should
169 * allocate dynamic storage of the appropriate size and return it.
