The XDR Representation, continued

XDR defines the representation of simple types, and the representation to be used when combining these types to produce more complex types.

The simple types include:

• integers, short and long, signed and unsigned
• floats, single and double precision
• characters, signed and unsigned
• enumerated types and Booleans

These may be combined to produce the complex types:

• fixed and variable length arrays
• strings
• structures
• discriminated unions

XDR also allows some special types:

• fixed and variable length opaque data
• the 'void' type
