Arithmetic Inserters | |
All the operator<< functions (aka formatted output functions) have some common behavior. Each starts by constructing a temporary object of type std::basic_ostream::sentry. This can have several effects, concluding with the setting of a status flag; see the sentry documentation for more.If the sentry status is good, the function tries to generate whatever data is appropriate for the type of the argument.
If an exception is thrown during insertion, ios_base::badbit will be turned on in the stream's error state without causing an ios_base::failure to be thrown. The original exception will then be rethrown. | |

__ostream_type & | operator<< (const void *__p) |
Basic arithmetic inserters. | |
__ostream_type & | operator<< (streambuf_type *sb) |

Unformatted Output Functions | |
All the unformatted output functions have some common behavior. Each starts by constructing a temporary object of type std::basic_ostream::sentry. This has several effects, concluding with the setting of a status flag; see the sentry documentation for more. If the sentry status is good, the function tries to generate whatever data is appropriate for the type of the argument.
If an exception is thrown during insertion, ios_base::badbit will be turned on in the stream's error state. If badbit is on in the stream's exceptions mask, the exception will be rethrown without completing its actions. | |
