Wed Apr 24 17:35:30 Ulrich Drepper * inet/netinet/in.h, socket/sys/socket.h: Move to sysdeps/generic/netinet/in.h, sysdeps/generic/sys/socket.h. * netinet/in.h, sys/socket.h: Remove file. * misc/Makefile (routines): Add fdatasync. * posix/Makefile (headers): Add sched.h. (routines): Add nanosleep, sched_setp, sched_getp, sched_sets, sched_gets, sched_yield, sched_primax, sched_primin, sched_rr_gi. * posix/getconf.c (vars): Add entries for _POSIX_REALTIME_SIGNALS, _POSIX_PRIORITY_SCHEDULING, _POSIX_TIMERS, _POSIX_ASYNCHRONOUS_IO, _POSIX_PRIORITIZED_IO, _POSIX_SYNCHRONIZED_IO, _POSIX_FSYNC, _POSIX_MAPPED_FILES, _POSIX_MEMLOCK, _POSIX_MEMLOCK_RANGE, _POSIX_MEMORY_PROTECTION, _POSIX_MESSAGE_PASSING, _POSIX_SEMAPHORES, _POSIX_SHARED_MEMORY_OBJECTS. * posix/sched.h: New file. Header for POSIX scheduling interface. * posix/unistd.h: Describe options from POSIX.4. Add declaration of fdatasync. * sysdeps/generic/confname.h: Add definition for _SC_REALTIME_SIGNALS, _SC_PRIORITY_SCHEDULING, _SC_TIMERS, _SC_ASYNCHRONOUS_IO, _SC_PRIORITIZED_IO, _SC_SYNCHRONIZED_IO, _SC_FSYNC, _SC_MAPPED_FILES, _SC_MEMLOCK, _SC_MEMLOCK_RANGE, _SC_MEMORY_PROTECTION, _SC_MESSAGE_PASSING, _SC_SEMAPHORES, _SC_SHARED_MEMORY_OBJECTS. * sysdeps/generic/fdatasync.c: New file. Default implementation simply uses fsync. * sysdeps/generic/netinit/in.h: Moved to here from inet/netinet/in.h. * sysdeps/generic/schedbits.h: New file. System dependent defintion for POSIX.4 scheduling interface. * sysdeps/generic/sys/socket.h: Moved to here from socket/sys/socket.h. * sysdeps/stub/nanosleep.c, sysdeps/stub/sched_getp.c, sysdeps/stub/sched_gets.c, sysdeps/stub/sched_primax.c, sysdeps/stub/sched_primin.c, sysdeps/stub/sched_rr_gi.c, sysdeps/stub/sched_setp.c, sysdeps/stub/sched_sets.c, sysdeps/stub/sched_yield.c: New file: Stub implementation for systems missing these POSIX.4 system calls. * sysdeps/unix/sysv/linux/gnu/types.h, sysdeps/unix/sysv/linux/ioctls.h: Use kernel header for data type definitions. * sysdeps/unix/sysv/linux/netinet/in.h: New file. Linux specific version. * sysdeps/unix/sysv/linux/posix_opt.h: New file. Define POSIX options applicable for Linux. * sysdeps/unix/sysv/linux/syscalls.list: Add definitions for fdatasync, nanosleep, sched_setparam, sched_getparam, sched_setscheduler, sched_getscheduler, sched_yield, sched_get_priority_max, sched_get_priority_min, and sched_rr_get_interval. * sysdeps/unix/sysv/linux/sysconf.c: Add handling of POSIX.4 options. * sysdeps/unix/sysv/linux/termbits.h: Use kernel headers. * time/sys/time.h: Remove definition of `struct timespec'. * time/time.h (struct timespec): Move definition to here. variable, LUCKY, to use instead of setting D to -1 (which fouls --- sysdeps/unix/sysv/linux/posix_opt.h | 57 +++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/posix_opt.h (limited to 'sysdeps/unix/sysv/linux/posix_opt.h') diff --git a/sysdeps/unix/sysv/linux/posix_opt.h b/sysdeps/unix/sysv/linux/posix_opt.h new file mode 100644 index 0000000000..d336335fc3 --- /dev/null +++ b/sysdeps/unix/sysv/linux/posix_opt.h @@ -0,0 +1,57 @@ +/* Define POSIX options for Linux. +Copyright (C) 1996 Free Software Foundation, Inc. +This file is part of the GNU C Library. + +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.
