strstreambuf::pcount
Returns a count of the number of elements written to the controlled sequence.
streamsize pcount( ) const;
Return Value
A count of the number of elements written to the controlled sequence.
Remarks
Specifically, if pptr is a null pointer, the function returns zero. Otherwise, it returns pptr – pbase.
Example
// strstreambuf_pcount.cpp
// compile with: /EHsc
#include <iostream>
#include <strstream>
using namespace std;
int main( )
{
strstream x;
x << "test1";
cout << x.rdbuf( )->pcount( ) << endl;
x << "test2";
cout << x.rdbuf( )->pcount( ) << endl;
}
