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
  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.
