cfsetispeed - set input baud rate
Návod, kniha: POSIX Programmer's Manual
#include <termios.h>
int cfsetispeed(struct termios *
termios_p,
speed_t speed);
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.
Upon successful completion,
cfsetispeed() shall return 0; otherwise, -1
shall be returned, and
errno may be set to indicate the 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>.
