CFSETOSPEED(3P) POSIX Programmer's Manual CFSETOSPEED(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
cfsetospeed — set output baud rate
#include <termios.h>
int cfsetospeed(struct termios *termios_p, speed_t speed);
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.
Upon successful completion, cfsetospeed() shall return 0; otherwise,
it shall return −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>.
The following sections are informative.
