virtual int sync()

If a put area exists (e.g. the file was opened for writing), calls Template:rlpf to write all pending output to the file.

If a get area exists (e.g. the file was opened for reading), the effect is implementation-defined. Typical implementation may empty out the get area and move the current file position back by the corresponding number of bytes.

Contents

Parameters

Return value

0 in case of success, -1 in case of failure.

Notes

sync() or its equivalent is implicitly called by Template:rlpf, Template:rlpf, and Template:rlpf and explicitly called by std::basic_streambuf::pubsync
