CFSETISPEED 3C "Jul 24, 2002"
NAME
cfsetispeed, cfsetospeed - set input and output baud rate
SYNOPSIS

#include <termios.h>

int cfsetispeed(struct termios *termios_p, speed_t speed);

int cfsetospeed(struct termios *termios_p, speed_t speed);
DESCRIPTION

The cfsetispeed() function sets the input baud rate stored in the structure pointed to by termios_p to speed.

The cfsetospeed() function sets the output baud rate stored in the structure pointed to by termios_p to speed.

There is no effect on the baud rates set in the hardware until a subsequent successful call to tcsetattr(3C) on the same termios structure.

RETURN VALUES

Upon successful completion, cfsetispeed() and cfsetospeed() return 0. Otherwise -1 is returned, and errno may be set to indicate the error.

ERRORS

The cfsetispeed() and cfsetospeed() functions may fail if: EINVAL

The speed value is not a valid baud rate.

EINVAL

The value of speed is outside the range of possible speed values as specified in <termios.h>.
