int pcount() const; |
Returns the number of characters that were output in the put area of the associated std::strstreambuf. Effectively calls rdbuf()->pcount().
(none).
The number of characters in the put area, or zero if nothing was output.
#include <strstream>
#include <iostream>
int main()
{
std::ostrstream 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::ostrstream user(buf, 10); // user-provided output buffer
user << 1.23; // note: no std::ends
std::cout.write(buf, user.pcount());
std::cout << '\n';
}Output:
The size of the output is 11 and it holds "Test: 1.23" 1.23
| returns the next pointer minus the beginning pointer in the output sequence: the number of characters written (public member function of std::strstreambuf) |
