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.
