+ * Name: tcgetattr
+ *
+ * Descripton:
+ *   The tcgetattr() function gets the parameters associated with the
+ *   terminal referred to by 'fd' and stores them in the termios structure
+ *   referenced by 'termiosp'.
+ *
+ * Input Parameters:
+ *   fd - The 'fd' argument is an open file descriptor associated with a terminal.
+ *   termiosp - The termiosp argument is a pointer to a termios structure.
+ *
+ * Returned Value:
+ *   Upon successful completion, 0 is returned. Otherwise, -1 is returned and
+ *   errno is set to indicate the error.  The following errors may be reported:
+ *
+ *   - EBADF: The 'fd' argument is not a valid file descriptor. 
+ *   - ENOTTY: The file associated with 'fd' is not a terminal. 
+ *
