(__finite): Mark function as const. Add inline code for __ieee754_atan2. * sysdeps/libm-ieee754/s_cacoshf.c: Add alternate implementation (but don't use it now). * sysdeps/libm-ieee754/s_catan.c: Use __ieee754_atan2 instead of __atan. * sysdeps/libm-ieee754/s_catanf.c: Likewise. * sysdeps/libm-ieee754/s_catanl.c: Likewise. * sysdeps/libm-ieee754/s_catanh.c: Likewise. Correct sign of real part. * sysdeps/libm-ieee754/s_catanhf.c: Likewise. * sysdeps/libm-ieee754/s_catanhl.c: Likewise. * sysdeps/libm-ieee754/s_clog10.c: Use factor to correct __ieee754_atan2 to base 10. * sysdeps/libm-ieee754/s_clog10f.c: Likewise. * sysdeps/libm-ieee754/s_clog10l.c: Likewise. * sysdeps/unix/sysv/linux/alpha/kernel_sigaction.h: Define as old_kernel_sigaction. * sysdeps/unix/sysv/linux/net/if_slip.h: Pretty print. * wctype/Makefile (routines): Add wctype_l. * wctype/wctype.h: Add declaration of __wctype_l. * wctype/wctype_l.c: New file. 1997-12-10 00:38 Ulrich Drepper * locale/C-ctype.c: Correct data for isw* functions. * locale/programs/ld-ctype.c: Write 32bit char classes in correct byte order. * wctype/test_wctype.c: Add test for isw* functions. * wctype/wctype.c: Return value with expected byte order. * sysdeps/generic/_G_config.h: Define _G_HAVE_IO_FILE_OPEN. * sysdeps/unix/sysv/linux/_G_config.h: Likewise. --- sysdeps/posix/waitid.c | 118 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 118 insertions(+) create mode 100644 sysdeps/posix/waitid.c (limited to 'sysdeps/posix/waitid.c') diff --git a/sysdeps/posix/waitid.c b/sysdeps/posix/waitid.c new file mode 100644 index 0000000000..a36883a8d2 --- /dev/null +++ b/sysdeps/posix/waitid.c @@ -0,0 +1,118 @@ +/* Pseudo implementation of waitid. + Copyright (C) 1997 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Zack Weinberg , 1997. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 of the + License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
