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(M)).
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(S)
for the effects of O_NONBLOCK on write).
