       Specifies a 16-bit integer in host byte order.

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

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

ERRORS    [Toc]    [Back]

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