cfsetospeed - set output baud rate
#include <termios.h> int cfsetospeed(struct termios *termios_p, speed_t 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() on the same termios structure.
Upon successful completion, cfsetospeed() returns 0. Otherwise it returns -1 and errno may be set to indicate the error.
The cfsetospeed() function 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>.
