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 available 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:\n";
 
         string str;
 
         if (!getline(cin, str))
             return 0;
 
         if (str == "")
             break;
 
         try
         {
             Hostname h(str);
 
             cout << "Official name:\n";
                 cout << h.hostname() << endl;
 
             cout << "Aliases:\n";
             for (size_t idx = 0; idx < h.nAliases(); idx++)
                 cout << h.alias(idx) << " ";
             cout << endl;
 
             cout << "Adresses:\n";
             for (size_t idx = 0; idx < h.nAddresses(); idx++)
                 cout << h.dottedDecimalAddress(idx) << " ";
             cout << endl;
         }
         catch (Errno const &err)
         {
             cout << err.what() << endl;
         }
     }
     return 0;
 }
