82 * "A record is composed of one or more record fragments. A record
83 * fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of
84 * fragment data. The bytes encode an unsigned binary number; as with
85 * XDR integers, the byte order is from highest to lowest. The number
86 * encodes two values -- a boolean which indicates whether the fragment
87 * is the last fragment of the record (bit value 1 implies the fragment
88 * is the last fragment) and a 31-bit unsigned binary value which is the
89 * length in bytes of the fragment's data. The boolean value is the
90 * highest-order bit of the header; the length is the 31 low-order bits.
91 * (Note that this record specification is NOT in XDR standard form!)"
93 * The Linux RPC client always sends its requests in a single record
94 * fragment, limiting the maximum payload size for stream transports to
