Throwing exceptions on errors.
If the error flage is already set when the exceptions mask is added, the exception is immediately thrown. Try running the following under GCC 3.1 or later: #include <iostream> #include <fstream> #include <exception> int main() { std::set_terminate (__gnu_cxx::__verbose_terminate_handler); std::ifstream f ("/etc/motd"); std::cerr << "Setting badbit\n"; f.setstate (std::ios_base::badbit); std::cerr << "Setting exception mask\n"; f.exceptions (std::ios_base::badbit); } Definition at line 243 of file basic_ios.h.

Access to integer array.

Changing the underlying buffer.
Due to historical accidents which the LWG refuses to correct, the I/O library suffers from a design error: this function is hidden in derived classes by overrides of the zero-argument
