The entire collection of attributes of a terminal is stored in a
structure of type struct termios. This structure is used
with the functions tcgetattr and tcsetattr to read
and set the attributes.
— Data Type: struct termios
Structure that records all the I/O attributes of a terminal. The
structure includes at least the following members:
A bit mask specifying flags for input modes; see Input Modes.
A bit mask specifying flags for output modes; see Output Modes.
A bit mask specifying flags for control modes; see Control Modes.
A bit mask specifying flags for local modes; see Local Modes.
An array specifying which characters are associated with various
control functions; see Special Characters.
The struct termios structure also contains members which
encode input and output transmission speeds, but the representation is
not specified. See Line Speed, for how to examine and store the
The following sections describe the details of the members of the
struct termios structure.
— Data Type: tcflag_t
This is an unsigned integer type used to represent the various
bit masks for terminal flags.
— Data Type: cc_t
This is an unsigned integer type used to represent characters associated
with various terminal control functions.
— Macro: int NCCS
The value of this macro is the number of elements in the c_cc
