Terminal device control

Writing data and output processing

When a process writes data onto a terminal-device-file, c_oflag controls how to process those bytes (see ``Output modes'' in termio(7)). UNIX System V provides buffering such that a call to write schedules data for transfer to the device, but has not necessarily completed the transfer when the call returns (see write(2) for the effects of O_NONBLOCK on write).
