cfsetospeed(3p)
NAME
cfsetospeed - set output baud rate
SYNOPSIS
#include <termios.h> int cfsetospeed(struct termios *termios_p, speed_t speed);
DESCRIPTION
The cfsetospeed() function shall set the output baud rate stored in the structure pointed to by termios_p to speed.
There shall be no effect on the baud rates set in the hardware until a
subsequent successful call to tcsetattr() with the same termios structure. Similarly, errors resulting from attempts to set baud rates not
supported by the terminal device need not be detected until the tcsetattr() function is called.
RETURN VALUE
Upon successful completion, cfsetospeed() shall return 0; otherwise, it
shall return -1 and errno may be set to indicate the error.
ERRORS
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>.
- The following sections are informative.
