or the interface may not be implemented on Linux.
Имя (Name)
cfsetispeed — set input baud rate
Синопсис (Synopsis)
#include <termios.h>
int cfsetispeed(struct termios *termios_p, speed_t speed);
Описание (Description)
The cfsetispeed() function shall set the input 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.
Возвращаемое значение (Return value)
Upon successful completion, cfsetispeed() shall return 0;
otherwise, -1 shall be returned, and errno may be set to indicate
the error.
Ошибки (Error)
The cfsetispeed() 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>.
