* Turn execvpe() into an internal libc routine.Ed Schouten2008-06-231-1/+0
| | | | | | | | | | | | | | | Adding exevpe() has caused some ports to break. Even though execvpe() is a useful routine, it does not conform to any standards. This patch is a little bit different from the patch sent to the mailing list. I forgot to remove execvpe from the Symbol.map (which does not seem to miscompile libc, though).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | different from what has been offered in libc_r (the one spotted in the original PR which is found in libthr has already been removed by David's commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h): - Use POSIX standard prototype for ttyname_r, which is, int ttyname_r(int, char *, size_t); Instead of: char *ttyname_r(int, char *, size_t); This is to conform IEEE Std 1003.1, 2004 Edition [1]. - Since we need to use standard errno for return code, include errno.h in ttyname.c - Update ttyname(3) implementation according to reflect the API change. - Document new ttyname_r(3) behavior - Since we already make use of a thread local storage for ttyname(3), remove the BUGS section. - Remove conflicting ttyname_r related declarations found in libc_r. Hopefully this change should not have changed the API/ABI, as the ttyname_r symbol was never introduced before the last unistd.h change which happens a couple of days before.

* Change the definition of NULL on ia64 (for LP64 compilations) fromMarcel Moolenaar2003-12-071-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an int constant to a long constant. This change improves consistency in the following two ways: 1. The first 8 arguments are always passed in registers on ia64, which by virtue of the generated code implicitly widens ints to longs and allows the use of an 32-bit integral type for 64-bit arguments. Subsequent arguments are passed onto the memory stack, which does not exhibit the same behaviour and consequently do not allow this. In practice this means that variadic functions taking pointers and given NULL (without cast) work as long as the NULL is passed in one of the first 8 arguments. A SIGSEGV is more likely the result if such would be done for stack-based arguments. This is due to the fact that the upper 4 bytes remain undefined. 2. All 64-bit platforms that FreeBSD supports, with the obvious exception of ia64, allow 32-bit integral types (specifically NULL) when 64-bit pointers are expected in variadic functions by way of how the compiler generates code. As such, code that works correctly (whether rightfully so or not) on any platform other than ia64, may fail on ia64. To more easily allow tweaking of the definition of NULL, this commit removes the 12 definitions in the various headers and puts it in a new header that can be included whenever NULL is to be made visible. This commit fixes GNOME, emacs, xemacs and a whole bunch of ports that I don't particularly care about at this time... Notes: svn path=/head/; revision=123257
