int ACE_INET_Addr::addr_to_string (  ACE_TCHAR    buffer[],
size_t    size,
int    ipaddr_format = 1
)  const [virtual]
 

Transform the current <ACE_INET_Addr> address into string format. If <ipaddr_format> is non-0 this produces "ip-number:port-number" (e.g., "128.252.166.57:1234"), whereas if <ipaddr_format> is 0 this produces "ip-name:port-number" (e.g., "tango.cs.wustl.edu:1234"). Returns -1 if the <size> of the <buffer> is too small, else 0.

void ACE_INET_Addr::set_port_number (  u_short   ,
int    encode = 1
) 
 

Sets the port number without affecting the host name. If <encode> is enabled then <port_number> is converted into network byte order, otherwise it is assumed to be in network byte order already and are passed straight through.

int ACE_INET_Addr::string_to_addr (  const char    address[] )  [virtual]
 

Initializes an <ACE_INET_Addr> from the <address>, which can be "ip-addr:port-number" (e.g., "tango.cs.wustl.edu:1234"), "ip-addr:port-name" (e.g., "tango.cs.wustl.edu:telnet"), "ip-number:port-number" (e.g., "128.252.166.57:1234"), or "ip-number:port-name" (e.g., "128.252.166.57:telnet"). If there is no ':' in the <address> it is assumed to be a port number, with the IP address being INADDR_ANY.
