XDR Constructed Filter Primitives
The XDR filter primitives are subroutines that define the basic and constructed data types. Constructed data type filters allow complex data types to be created from basic data types.
Constructed data types require more parameters to perform more complicated functions than do basic data types. Memory management is an example of a more complicated function that can be performed with the constructed primitives. Memory is allocated when deserializing data with the xdr_decode subroutine. Memory is deallocated through the xdr_free subroutine.
The constructed data-type filter primitives include the following:
