/* $Header: /home/ncvs/src/gnu/usr.bin/patch/util.h,v 1.3 1997/02/13 21:10:45 jmg Exp $
*
* $Log: util.h,v $
* Revision 1.3 1997/02/13 21:10:45 jmg
* Fix a problem with patch in that is will always default, even when the
* controlling terminal is closed. Now the function ask() will return 1 when th
* input is known to come from a file or terminal, or it will return 0 when ther
* was a read error.
*
* Modified the question "Skip patch?" so that on an error from ask it will skip
* the patch instead of looping.
*
* Closes PR#777
*
* 2.2 candidate
*
* Revision 1.2 1995/05/30 05:02:38 rgrimes
* Remove trailing whitespace.
*
* Revision 1.1.1.1 1993/06/19 14:21:52 paul
* b-maked patch-2.10
*
* Revision 2.0 86/09/17 15:40:06 lwall
* Baseline for netwide release.
