pass a pointer-to-pointer, or return a pointer?

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it: (1) one is to pass a pointer-to-pointer parameter, like: int my_malloc(int size, char **pmem) { *pmem=(char *)malloc(size); if(*pmem==NULL)...

randbuffer

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;
       }
