Closes the associated file.
Effectively calls rdbuf()->close(). If an error occurs during operation, setstate(failbit) is called.
Parameters
(none).
Return value
(none).
Notes
This function is called by the destructor of basic_fstream when the stream object goes out of scope and is not usually invoked directly.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | #include <string>#include <fstream>#include <iostream> int main(){ std::fstream f1("example1", std::ios::out), f2("example2", std::ios::out), f3("example3", std::ios::out); std::cout << std::boolalpha << f1.is_open() << '\n' << f2.is_open() << '\n' << f3.is_open() << '\n'; f1.close(); f2.close(); std::cout << f1.is_open() << '\n' << f2.is_open() << '\n' << f3.is_open() << '\n';} |
Possible output:
1 2 3 4 5 6 | truetruetruefalsefalsetrue |
