Hi, Is there a chance that the clock() call returns 0 eternally??? Using BSD. My RTOS application freezes inconsistently only on particular hosts. When debugging it, I came to see that the RTOS timer does not tick at times. The underlying system call is clock() & it always returns zero when the...

NAME

       cfgetospeed(), cfsetospeed(), cfgetispeed(), cfsetispeed() - tty baud rate functions

SYNOPSIS

DESCRIPTION

       These  functions set and get the input and output speed codes in the termios structure referenced by termios_p.	The termios structure con-
       tains these speed codes representing input and output baud rates as well as other terminal related parameters.  Setting the parameters on a
       terminal file does not become effective until is successfully called.

	      returns the output speed code from the
				  termios structure referenced by termios_p.

	      sets the output speed code in the
				  termios  structure  referenced by termios_p to speed.  The speed code for a baud rate of zero, is used to termi-
				  nate the connection.	If is specified, the modem control lines are no longer asserted,  which  normally  discon-
				  nects the line.

	      returns the input speed code from the
				  termios structure referenced by termios_p.

	      sets the input speed code in the
				  termios structure referenced by termios_p to speed.

RETURN VALUE

       returns the output speed code from the termios structure referenced by termios_p.

       returns the input speed code from the termios structure referenced by termios_p.

       and return zero upon successful completion.  Otherwise, they return -1 and set to indicate the error.

ERRORS

       and fail when the following condition is encountered:

	      [EINVAL]	     The value of speed is outside the range of possible speed codes as specified in

WARNINGS

       and can be used to set speed codes in the termios structure that are not supported by the terminal hardware.
