From ab4745dcb21ead97ebc469f93609a0b4a451f778 Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Thu, 15 Feb 2001 02:04:55 +0000 Subject: 2001-02-14 Kazuhiro Fujieda * libc/include/stdlib.h: Add declarations of rand48 functions and their reentrant versions. * libc/include/sys/reent.h: Move macros from rand48.h. Add struct _rand48 for shared parameters of rand48 functions. (struct _reent): Add a variable _r48 of struct _rand48. (_REENT_INIT): Add _r48 initialization. * libc/stdlib/Makefile.am (lib_a_SOURCES): Add rand48 functions. (CHEWOUT_FILES): Add rand48.def. * libc/stdlib/Makefile.am: Add dependencies for rand48 functions. * libc/stdlib/Makefile.in: Regenerated. * libc/stdlib/drand48.c (drand48, _drand48_r): Derived from the NetBSD C library. * libc/stdlib/erand48.c (erand48, _erand48_r): Ditto. * libc/stdlib/jrand48.c (jrand48, _jrand48_r): Ditto. * libc/stdlib/lcong48.c (lcong48, _lcong48_r): Ditto. * libc/stdlib/lrand48.c (lrand48, _lrand48_r): Ditto. * libc/stdlib/mrand48.c (mrand48, _mrand48_r): Ditto. * libc/stdlib/nrand48.c (nrand48, _nrand48_r): Ditto. * libc/stdlib/seed48.c (seed48, _seed48_r): Ditto. * libc/stdlib/srand48.c (srand48, _srand48_r): Ditto. * libc/stdlib/rand48.c (__dorand48): Ditto. * libc/stdlib/rand48.h: Ditto, and modify declarations of global parameters into macros referring them in the reentrant structure. --- newlib/libc/stdlib/seed48.c | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 newlib/libc/stdlib/seed48.c (limited to 'newlib/libc/stdlib/seed48.c') diff --git a/newlib/libc/stdlib/seed48.c b/newlib/libc/stdlib/seed48.c new file mode 100644 index 000000000..3f2cb5061 --- /dev/null +++ b/newlib/libc/stdlib/seed48.c @@ -0,0 +1,43 @@ +/* + * Copyright (c) 1993 Martin Birgmeier + * All rights reserved. + * + * You may redistribute unmodified or modified versions of this source + * code provided that the above copyright notice and this and the + * following conditions are retained. + * + * This software is provided ``as is'', and comes with no warranties + * of any kind.
