14 \fBXDR\fR library routines allow C programmers to describe arbitrary data
  15 structures in a machine-independent fashion. Protocols such as remote procedure
  16 calls (RPC) use these routines to describe the format of the data.

  23 See \fBrpc\fR(3NSL) for the definition of the \fBXDR\fR data structure. Note
  24 that any buffers passed to the \fBXDR\fR routines must be properly aligned.  It
  25 is suggested either that \fBmalloc\fR(3C) be used to allocate these buffers, or
  26 that the programmer insure  that the buffer address is divisible evenly by
  27 four.
