hostname
FBB::Hostname(3bobcat) Host Info FBB::Hostname(3bobcat)
NAME
FBB::Hostname - Contains name/address info about a host
SYNOPSIS
#include <bobcat/hostname>
Linking option: -lbobcat
DESCRIPTION
FBB::Hostname objects inherit from Hostent, and offers information about a host, like Hostent. Apart from being initialized by a hostname
or host address, they can also be initialized by a FBB::InetAddress object. Most of the functionality of an FBB::Hostname object is avail-
able through its parent-class FBB::Hostent.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
INHERITS FROM
FBB::Hostent
CONSTRUCTORS
o Hostname():
The default constructor initializes an empty FBB::Hostname object.
o Hostname((std::string const &host)):
This constructor initializes an FBB::Hostname object from a string representing the name or dotted decimal address of a host. An
FBB::Errno object is thrown if the hostname information could not be retrieved.
o Hostname(InetAddress const &inetAddress):
This constructor initializes an FBB::Hostname object from an InetAddress object. An FBB::Errno object is thrown if the hostname
information could not be retrieved. The copy constructor is available.
MEMBER FUNCTIONS
All members of FBB::Hostent are available, as FBB::Hostname inherits from this class. There are no additional members.
EXAMPLE
#include <iostream>
#include <bobcat/hostname>
#include <bobcat/errno>
using namespace std;
using namespace FBB;
int main(int argc, char **argv)
{
while (true)
{
cout << "Enter name or address:
";
string str;
if (!getline(cin, str))
return 0;
if (str == "")
break;
try
{
Hostname h(str);
cout << "Official name:
";
cout << h.hostname() << endl;
cout << "Aliases:
";
for (size_t idx = 0; idx < h.nAliases(); idx++)
cout << h.alias(idx) << " ";
cout << endl;
cout << "Adresses:
";
for (size_t idx = 0; idx < h.nAddresses(); idx++)
cout << h.dottedDecimalAddress(idx) << " ";
cout << endl;
}
catch (Errno const &err)
{
cout << err.why() << endl;
}
}
return 0;
}
