1/* mpz_init_set_str(string, base) -- Convert the \0-terminated string 2 STRING in base BASE to a multiple precision integer. Return a MP_INT 3 structure representing the integer. Allow white space in the 4 string. If BASE == 0 determine the base in the C standard way, 5 i.e. 0xhh...h means base 16, 0oo...o means base 8, otherwise 6 assume base 10. 7 8Copyright 1991, 1993, 1994, 1995, 2000, 2001, 2002 Free Software Foundation, 9Inc. 10 11This file is part of the GNU MP Library. 12 13The GNU MP Library is free software; you can redistribute it and/or modify 14it under the terms of the GNU Lesser General Public License as published by 15the Free Software Foundation; either version 3 of the License, or (at your 16option) any later version. 17 18The GNU MP Library is distributed in the hope that it will be useful, but 19WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY 20or FITNESS FOR A PARTICULAR PURPOSE.
