Grimes.Sh DESCRIPTION 5458f0484fSRodney W. GrimesThese routines convert 16 and 32 bit quantities between network 5558f0484fSRodney W. Grimesbyte order and host byte order. 5658f0484fSRodney W. GrimesOn machines which have a byte order which is the same as the network 5758f0484fSRodney W. Grimesorder, routines are defined as null macros. 5858f0484fSRodney W. Grimes.Pp 5958f0484fSRodney W.
