Contents
[edit] Parameters
 ch
 -
 character to write
[edit] Return value
The written character, converted to int_type with Traits::to_int_type(ch) on success.
Traits::eof() (as returned by overflow() ) on failure.
[edit] Example
Run this code
#include <iostream> #include <sstream> int main() { std::ostringstream s; s.rdbuf()->sputc('a'); std::cout << s.str() << '\n'; }
Output:
