TCSETA, TCSETAF, TCSETAW

Set terminal properties from a termio structure

Synopsis:

#include <sys/ioctl.h>

#define TCSETA          _IOW('T', 2, struct termio)
#define TCSETAW         _IOW('T', 3, struct termio)
#define TCSETAF         _IOW('T', 4, struct termio)

Arguments to ioctl():

Argument	Value
`fd`	A file descriptor that you obtained by opening the device
`request`	TCSETA, TCSETAF, or TCSETAW
Additional argument	A pointer to a struct termio

Description:

These commands change the current terminal control settings of a device:

TCSETA — make the change immediately
TCSETAF — Don't make the change until all currently written data has been transmitted, at which point any received but unread data is also discarded.
TCSETAW — don't make the change until all currently written data has been transmitted.

Note: These commands are for internal use, and you shouldn't use them directly. Instead use the tcsetattr() cover function.

The TCSETS, TCSETSF, and TCSETSW ioctl() commands are similar, but they use a struct termios instead of a struct termio.

Input:

A termio structure.

Output:

None.
