Encode constant TLV-TYPE and TLV-LENGTH to unaligned_uint16_t constant.

Parameters

type	TLV-TYPE number, compile-time constant less than 0xFD.
length	TLV-LENGTH number, compile-time constant no more than 0xFF.

			length )

Value:

  __extension__({                                                                                  \

  })

Encode constant TLV-TYPE and TLV-LENGTH to unaligned_uint32_t constant.

Parameters

type	TLV-TYPE number, compile-time constant between 0xFD and 0xFFFF.
length	TLV-LENGTH number, compile-time constant no more than 0xFF.
