integer = %SS_HTONL(hostlong)
Return value

Returns a long integer in network byte order. (i4)
Arguments
hostlong
A long integer in host byte order. (i4)
Discussion
%SS_HTONL converts 32-bit (long) unsigned integers from host byte order (native endian type) to network byte order.
Host byte order is the format in which bytes are ordered internally on a specific host. Network byte order is the format in which data bytes are supposed to be transmitted through a network. All hosts on a network must send data in network byte order. If your host does not have an internal data representation format identical to the network byte order, you must use %SS_HTONL.

In the Synergy socket API, all IP address and port arguments (in_addr and in_port) are in host byte order, and should not be converted to network byte order. The %SS_HTONL function should only be used when sending portable data over the network. |
