128 | * XDR provides a conventional way for converting between C data | |
129 | * types and an external bit-string representation. Library supplied | |
130 | * routines provide for the conversion on built-in C data types. These | |
131 | * routines and utility routines defined here are used to help implement | |
132 | * a type encode/decode routine for each user-defined type. | |
133 | * | |
134 | * Each data type provides a single procedure which takes two arguments: | |
135 | * | |
136 | * bool_t | |
137 | * xdrproc(xdrs, argresp) | |
138 | * XDR *xdrs; | |
139 | * <type> *argresp; | |
140 | * | |
141 | * xdrs is an instance of a XDR handle, to which or from which the data | |
142 | * type is to be converted. argresp is a pointer to the structure to be | |
143 | * converted. The XDR handle contains an operation field which indicates | |
144 | * which of the operations (ENCODE, DECODE * or FREE) is to be performed. | |
145 | * | |
146 | * XDR_DECODE may allocate space if the pointer argresp is null. This | |
147 | * data can be freed with the XDR_FREE operation. | |
148 | * | |
149 | * We write only one procedure per data type to make it easy | |
150 | * to keep the encode and decode procedures for a data type consistent. | |
151 | * In many cases the same code performs all operations on a user defined type, | |
152 | * because all the hard work is done in the component type routines. | |
