NAME

cfsetispeed − Set input baud rate for a terminal

SYNOPSIS

#include <termios.h>
int cfsetispeed(
        struct termios ∗termios_p,
        speed_t speed );

LIBRARY

Standard C Library (libc)

STANDARDS

Interfaces documented on this reference page conform to industry standards as follows:

cfsetispeed():  POSIX.1, XPG4, XPG4-UNIX

Refer to the standards(5) reference page for more information about industry standards and associated tags. 

PARAMETERS

termios_p
Points to a termios structure containing the input baud rate. 

speed
Specifies the new input baud rate.

DESCRIPTION

The cfsetispeed() function sets the input baud rate stored in the structure pointed to by the termios_p parameter to the value specified by the speed parameter. 

If the input baud rate is set to 0 (zero), the input baud rate will be specified by the value of the output baud rate. 

There is no effect on the baud rates set in the hardware until a subsequent successful call is made to the tcsetattr() function on the same termios structure. 

RETURN VALUES

Upon successful completion, the cfsetispeed() function returns a value of 0 (zero). Otherwise, a value of -1 is returned.
