cfsetispeed
cfsetispeed(3) Library Functions Manual cfsetispeed(3)
NAME
cfsetispeed - Sets input baud rate for a terminal
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <termios.h>
int cfsetispeed( struct termios *termios_p; speed_t speed);
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
Points to a termios structure containing the input baud rate. 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.
