Module: Standard C++ Library Library: Input/output
Predefined stream that controls output to a stream buffer associated with the object stderr declared in <cstdio>
#include <iostream>
namespace std {
extern ostream cerr;
}
The object cerr controls output to a stream buffer associated with the object stderr declared in <cstdio>. By default, the standard C and C++ streams are synchronized, but you can improve performance by using the ios_base member function synch_with_stdio to desynchronize them.
The formatting is done through member functions or manipulators. See cout or basic_ostream for details.
