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