cfsetispeed(3)
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(3) 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>.
