cfsetispeed(3C) 					   Standard C Library Functions 					   cfsetispeed(3C)

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>.
