NAME

cfsetospeed - set output baud rate

SYNOPSIS

#include <termios.h>

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

DESCRIPTION

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.

RETURN VALUE

Upon successful completion, cfsetospeed() returns 0. Otherwise it returns -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>.

EXAMPLES

None.

APPLICATION USAGE

None.

FUTURE DIRECTIONS

None.
