FBB::Hostent(3bobcat)					      struct hostent wrapper					     FBB::Hostent(3bobcat)

NAME

       FBB::Hostent - Wrapper around a struct hostent

SYNOPSIS

       #include <bobcat/hostent>
       Linking option: -lbobcat

DESCRIPTION

       @CLASS objects are wrappers around hostent structs which may be used by other objects. A struct hostent is defined as follows:

	   struct hostent
	   {
	       char    *h_name;        // official name of host
	       char    **h_aliases;    // alias list
	       int     h_addrtype;     // host address type (always AF_INET)
	       int     h_length;       // length of address
	       char    **h_addr_list;  // list of addresses
	   }

       The address fields are binary values of the addresses, each address requiring h_length bytes, the last address being equal to 0. The @CLASS
       objects offer a C++-like interface to this struct.

NAMESPACE

       FBB
       All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

CONSTRUCTORS

       o      Hostent(hostent const *hostentPtr):
	      This constructor initializes an @CLASS object from an existing hostent struct.  Functions  like  gethostbyname(3)  and  gethostbyad-
	      dress(3) return pointers to hostent structs.

       The default, copy and move constructors are available.

MEMBER FUNCTIONS

       o      size_t addressLength() const:
	      This member returns the length of the binary addresses in bytes.

       o      size_t addressType() const:
	      This member returns the type of the address. Currently this is always AF_INET.

       o      char const *alias(size_t index) const:
	      This member returns alias `index' of the host. The first alias has index 0. If alias `index' does not exist, 0 is returned.

       o      char const * const *beginAlias() const:
	      This member returns an iterator to the first alias. The hostname itself is not included in the list of aliases.

       o      char const *binaryAddress(size_t index) const:
	      This  member returns the binary address `index' of the host.  The first address has index 0. If address `index' does not exist, 0 is
	      returned. The pointer to the binary address points to a series of addressLength() bytes. Note that the returned address is  in  net-
	      work byte order. It can be converted to host byte order by the functions described in byteorder(3).

       o      std::string dottedDecimalAddress(size_t index) const:
	      This  member returns address `index' as a dotted decimal address in a string. The first address has index 0. If address `index' does
	      not exist, an empty string is returned.

       o      char const * const *endAlias() const:
	      This member returns an iterator pointing beyond the last alias.

       o      char const *hostname() const:
	      This member returns the standard (first) name of the host.

       o      size_t nAddresses() const:
	      This member returns the number of addresses that are available. When requesting a particular address, the requested index should	be
	      less than the value returned by this member.

       o      size_t nAliases() const:
	      This member returns the number of aliases that are available. When requesting a particular alias, the requested index should be less
	      than the value returned by this member.

       o      void swap(Hostent &other):
	      The current Hostent object's contents are swapped with the other object's contents.

       The overloaded assignment operator and the move-aware overloaded assignment operators are available.

EXAMPLE

	   #include <iostream>
	   #include <algorithm>
	   #include <iterator>
	   #include <bobcat/hostent>

	   using namespace std;
	   using namespace FBB;

	   int main(int argc, char **argv)
	   {
	       Hostent he(gethostbyname("localhost"));

	       cout << "The local hostname = " << he.hostname() << endl;

	       cout << "All aliases: " << endl;
	       copy(he.beginAlias(), he.endAlias(),
			   ostream_iterator<char const *>(cout, "
"));

	       cout << "Addresses:
";
	       for (size_t idx = 0; idx < he.nAddresses(); idx++)
		   cout << he.dottedDecimalAddress(idx) << endl;

	       return 0;
	   }
