* Fix the style of the SCM ID's.David E. O'Brien2002-03-221-2/+2
| | | | | | | I believe have made all of libc .c's as consistent as possible. Notes: svn path=/head/; revision=92986
* Avoid getting stuck in system(3) when the internal call to wait4()Alfred Perlstein2001-10-031-2/+3
| | | | | | | | | | | | | is interrupted by saving the pid. The old code would assign the return value to pid which would trash it, to fix the problem save a copy of the pid to be used as the paramter to wait4().

* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579
* Take care to avoid having "strong" and "weak" symbols of the same name inJason Evans2000-03-161-0/+2

* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),Jason Evans2000-01-271-3/+2
| | | | | | | | | | | | | | | | | | | | just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant.

* Add three-tier symbol naming in support of POSIX thread cancellationJason Evans2000-01-121-2/+8
| | | | | | | | | points. For library functions, the pattern is __sleep() <-- _libc_sleep() <-- sleep(). The arrows represent weak aliases. For system calls, the pattern is _read() <-- _libc_read() <-- read(). Notes: svn path=/head/; revision=55837

| | | | | | | | | | | | | | | | | | | by W.Richard Ste vens. EINTR handling suggested by bde@freebsd.org). Code cleanup: 1. Add missing return type. 2. Replace 'union wait' by int. 3. Use Posix-style signal handling instead of signal(). 4. Use fork() instead of deprecated vfork(). 5. Block signals before fork()'ing, instead of after. 6. Return -1 if fork() fails, instead of 0. 7. Add EINTR handling for waitpid() call. Also add claim of Posix conformance to man page. Notes: svn path=/head/; revision=16117
