Submitted-by: ian@airs.com (Ian Lance Taylor) I want to read up to 4096 characters from the terminal in non-canonical mode. I want to wait until the characters arrive (with a timeout). It seems sensible to me to set MIN to the number of characters I want to read and use alarm for a timeout. But what is the maximum value that I can set MIN to on a POSIX system? Does the standard specify this anywhere? On System V the maximum is probably 255, but it's pretty easy to imagine an implementation for which the maximum is 127. I assume the maximum value is <= MAX_INPUT; are there any other constraints? I've only seen the 1988 copy of the standard, so apologies if this is covered in the 1990 revision. -- Ian Taylor ian@airs.com uunet!airs!ian First person to identify this quote wins a free e-mail message: ``If he could have moved, he would have gotten up and gone after the man to thank him for wearing something so marvelously interesting.''
