XDR Data Types and their Filter Primitives

The XDR standard defines basic and constructed data types. The XDR filter primitives are routines that define the basic and constructed data types. The XDR language provides RPC programmers with a specification for uniform representation that includes filter primitives for basic and constructed data types.

The basic data types include:

• Integers
  
• Enumeration
  
• Booleans
  
• Floating point decimals
  
• Void
  
• Constants
  
• Typedef
  
• Optional data

The constructed data types include:

• Arrays 
  Opaque data
  
  Strings
  
  Byte arrays
  
  Structures
  
  Discriminated unions
  
  Pointers
