my own stty command for linux-help with error?

[drunkenmonk]

I'm writing a lite version of the stty command for school, and I keep getting this error at compile:

showtty.c:40: error: expected ‘;’, ‘,’ or ‘)’ before ‘&’ token

My code:

#include	<stdio.h>
#include 	<stdlib.h>
#include	<termios.h>

/**
 **	showtty	
 **	displays some of current tty settings
 **/

main(int argc, char *argv[])
{
	struct	termios ttyinfo;				/*this struct holds tty info*/
	if (argc == 1)
	{						
		if ( tcgetattr( 0 , &ttyinfo ) == -1 )		/*get info*/
		{   					
			perror("cannot get params about stdin");
			exit(1);
		}
		show(&ttyinfo);					/*show info*/
		printf("\n");
	}
	else
	{
		int ii = 1;
		int offon = 1;
		while (ii < argc)
		{
			if (argv[ii][0] == '-')
				offon = 0;

			setbit( offon, &ttyinfo, argv[ii]);

		}


	}
}

setbit(int flip, struct termios *ttyi, char &option)
{
	if (flip == 0)
	{

Any thoughts?

[sree_ec]

one thing is

you are receiving something as &option.. this is not possible. if you mean to pass a pointer , u should receive it as *option as you have used for your second argument ttyi

also find another way other than switch to compare the values since you are passing string

[sree_ec]

one more thing i noted is that for switch, u have used 2 closing braces ')'.
this is also not needed
