PARAMETERS

       Specifies an open file descriptor associated with a terminal.  Points to a termios structure.

DESCRIPTION

       The  tcgetattr() function gets the parameters associated with the object referenced by the filedes parameter and stores them in the termios

RETURN VALUES

       Upon successful completion, 0 (zero) is returned. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The filedes parameter is not a valid file descriptor.  The file associated with the filedes parameter is not a terminal.
