CFSETISPEED(3C) Standard C Library Functions CFSETISPEED(3C)

cfsetispeed, cfsetospeedset input and output baud rate

#include <termios.h>

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

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

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

The () 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.

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

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

The speed value is not a valid baud rate.
The value of speed is outside the range of possible speed values as specified in <termios.h>.
