NAME
       std::strstream::pcount -	std::strstream::pcount

Synopsis
	  int pcount() const;

	  Returns the number of	characters that	were output in the put area of
       the associated
	  std::strstreambuf. Effectively calls rdbuf()->pcount()

Parameters
	  (none)

Return value

       output.

Example
       // Run this code

	#include <strstream>
	#include <iostream>

	int main()
	{
	    std::strstream dyn;	// dynamically-allocated output	buffer
	    dyn	<< "Test: " << 1.23 << std::ends;
	    std::cout << "The size of the output is " << dyn.pcount()
		      << " and it holds	\"" << dyn.str() << "\"\n";
	    dyn.freeze(false);

	    char buf[10];
	    std::strstream user(buf, 10); // user-provided output buffer
	    user << 1.23; // note: no std::ends
	    std::cout.write(buf, user.pcount());
	    std::cout << '\n';
	}
