cfmakeraw - set terminal raw mode
LIBRARY

SYNOPSIS
#define _DEFAULT_SOURCE /* See feature_test_macros(7) */ #include <termios.h>
void cfmakeraw(struct termios *termios_p);
DESCRIPTION
cfmakeraw() sets the terminal to something like the "raw" mode of the old Version 7 terminal driver: input is available character by character, echoing is disabled, and all special processing of terminal input and output characters is disabled.
The terminal attributes are set as follows:
termios_p->c_iflag &= ~(IGNBRK | BRKINT | PARMRK | ISTRIP
| INLCR | IGNCR | ICRNL | IXON);
termios_p->c_oflag &= ~OPOST;
termios_p->c_lflag &= ~(ECHO | ECHONL | ICANON | ISIG | IEXTEN);
termios_p->c_cflag &= ~(CSIZE | PARENB);
termios_p->c_cflag |= CS8;
RETURN VALUE
- 0
-
on success.
- -1
-
on failure and set errno to indicate the error.
