streambuf & csdbg::streambuf::flush ( )

pure virtual

To be implemented.

Flush the buffered data to the stream.

Returns

*this

Exceptions

i32

(errno)

Note

The buffer remains as is, if the stream isn't open

Synchronous output is enforced (even if O_NONBLOCK is specified)

Implemented in csdbg::sttybuf, csdbg::tcpsockbuf, and csdbg::filebuf.
