tty manipulation

[Devi reman]

I need to replicate a key press twice so that the action assocated with key press occurs in a single shot. the belwo code i have implemented for the same.

fd = open("/dev/pts/10", O_RDONLY); 
if(fd==-1) 
{ 
 return(0);  
} 
simulate_key = -K_F2; 
rc = ioctl(fd, TIOCSTI,simulate)
close(fd);

but while running i am getting error after the ioctl command that "A file descriptor does not represent an open file"

Thanks in advance
