This section describes the terminal flags and fields that control how
output characters are translated and padded for display. All of these
are contained in the
c_oflag member of the
c_oflag member itself is an integer, and you change the flags
and fields using the operators
try to specify the entire value for
only specific flags and leave the rest untouched (see Setting Modes).
If this bit is set, output data is processed in some unspecified way so that it is displayed appropriately on the terminal device. This typically includes mapping newline characters (
'\n') onto carriage return and linefeed pairs.
If this bit isn't set, the characters are transmitted as-is.
The following three bits are BSD features, and they exist only BSD
systems and the GNU system. They are effective only if
If this bit is set, convert the newline character on output into a pair of characters, carriage return followed by linefeed.
If this bit is set, convert tab characters on output into the appropriate number of spaces to emulate a tab stop every eight columns.
