/*
|
|
* From RFC 1831:
|
|
*
|
|
* "A record is composed of one or more record fragments. A record
|
|
* fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of
|
|
* fragment data. The bytes encode an unsigned binary number; as with
|
|
* XDR integers, the byte order is from highest to lowest. The number
|
|
* encodes two values -- a boolean which indicates whether the fragment
|
|
* is the last fragment of the record (bit value 1 implies the fragment
|
|
* is the last fragment) and a 31-bit unsigned binary value which is the
|
|
* length in bytes of the fragment's data. The boolean value is the
|
|
* highest-order bit of the header; the length is the 31 low-order bits.
|
|
* (Note that this record specification is NOT in XDR standard form!)"
|
|
*
|
|
* The Linux RPC client always sends its requests in a single record
|
|
* fragment, limiting the maximum payload size for stream transports to
|
|
* 2GB.
