FBB::RandBuffer(3bobcat) random number streambuf FBB::RandBuffer(3bobcat) NAME
FBB::RandBuffer - std::streambuf generating random numbers SYNOPSIS
#include <bobcat/randbuffer> Linking option: -lbobcat DESCRIPTION
FBB:RandBuffer objects may be used as a std::streambuf of std::istream objects to allow the extraction of random numbers from the stream. NAMESPACE
FBB All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB. INHERITS FROM
std::streambuf CONSTRUCTOR
o Randbuffer(int min, int max, size_t seed = 1): This Randbuffer() constructor initializes the random generator. The seed is used to initialze the random number generator.Random values between min and max (inclusive) are returned. VIRTUAL MEMBERS
o int underflow(): This function is called by std::istream objects using Randbuffer. It produces the next available random number, separating the ran- dom numbers by one blanks space. Random values between min and max (inclusive) are returned (see the description of the construc- tor). INHERITED MEMBERS
Since the class uses public derivation from std::streambuf, all members of this class can be used. EXAMPLE
#include <iostream> #include <istream> #include <bobcat/randbuffer> #include <bobcat/a2x> using namespace std; using namespace FBB; int main(int argc, char **argv) { if (argc == 1) { cout << "expect: nruns min max seed "; return 1; } Randbuffer rb(A2x(argv[2]), A2x(argv[3]), A2x(argv[4]).to<size_t>()); istream istr(&rb); for (int idx = A2x(argv[1]); idx--; ) { int c; if (!(istr >> c)) { cout << "extraction failed "; break; } cout << "next: " << c << endl; } int count = 0; while (istr.unget()) count++; cout << "number of successful unget()-calls: " << count << endl; istr.clear(); istr >> count; cout << "and read: " << count << endl; return 0; } FILES

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; } FILES
