       ntohl  -  Convert an unsigned 32-bit integer from Internet
       network byte order to host byte order

SYNOPSIS    [Toc]    [Back]

       #include <arpa/inet.h>

       in_addr_t ntohl(
               in_addr_t netint );

PARAMETERS    [Toc]    [Back]

       Specifies a 32-bit integer in network-byte order.

DESCRIPTION    [Toc]    [Back]

       The ntohl() (network-to-host long)  function  converts  an
       unsigned  32-bit  integer from Internet network-byte order
       to host-byte order.

       The Internet network requires address and  port  reference
       data  in network-byte order. You can use the ntohl() function
 to convert Internet network address and port data  to
       host byte-ordered integers.

RETURN VALUES    [Toc]    [Back]

       The ntohl() function returns a 32-bit integer in host-byte
       order.

ERRORS    [Toc]    [Back]

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