Allow white space in the string. 3 If BASE == 0 determine the base in the C standard way, i.e. 0xhh...h means 4 base 16, 0oo...o means base 8, otherwise assume base 10. 5 6Copyright 1991, 1993-1995, 2000-2002, 2012 Free Software Foundation, Inc. 7 8This file is part of the GNU MP Library. 9 10The GNU MP Library is free software; you can redistribute it and/or modify 11it under the terms of either: 12 13 * the GNU Lesser General Public License as published by the Free 14 Software Foundation; either version 3 of the License, or (at your 15 option) any later version. 16 17or 18 19 * the GNU General Public License as published by the Free Software 20 Foundation; either version 2 of the License, or (at your option) any 21 later version. 22 23or both in parallel, as here. 24 25The GNU MP Library is distributed in the hope that it will be useful, but 26WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY 27or FITNESS FOR A PARTICULAR PURPOSE.
