PARAMETERS
  hostshort Specifies a 16-bit integer in host byte order.

DESCRIPTION
  The htons() (host-to-network short) function converts an unsigned short
  (16-bit) integer from host byte order to Internet network-byte order.

  The Internet network requires address and port reference data in network-
  byte order.  Use the htons() function to convert address and port short
  integers from host byte order to Internet network-byte order.

RETURN VALUES
  Upon successful completion, the htons() function returns a 16-bit short
  integer in Internet network-byte order.

ERRORS
  Current industry standards do not define error values for the htons()
  function.
