Re: IO

["Robbie" <sheriff@excite.com>]

I'm not sure why but I created a char *, write the char to it and it works that way instead of including the hex in the write function; something like write(fd, mychar, 1) instead of write(fd, "0x16",1).
difference?
Is this the only way for user program to write bytes to an IO?


Thanks,

Seeing the (eventually reduced) source codeis basically the only way to get helpful advices.	Gabriel.
