cfsetispeed: set input baud rate
PROLOGThis 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.
cfsetispeed - set input baud rate
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.
The cfsetispeed() function may fail if:
- The speed value is not a valid baud rate.
The value of speed is outside the range of possible speed values
as specified in <termios.h>.
