Change the definition of NULL on ia64 (for LP64 compilations) from

2003-12-07T21:10:06Z

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...

Fix namespace issues by using the relatively new visibility

primitives.

style(9): line up function names.

Breath deep and take __P out of the system include files.

# This appears to not break X11, but I'm having problems compiling the # glide part of the server with or without this patch, so I can't tell # for sure.

Add a lock to DIR to make telldir and friends MT-safe.

2001-01-24T13:01:47Z

Clean up stdio.h a bit and remove _THREAD_SAFE. Some of the usual macros getc, putc, getchar, putchar are no longer macros. Approved by: -arch

Move telldir position recording type definitions and prototypes

2000-12-11T04:00:36Z

to "telldir.h" in order to prevent namespace pollution in (which was including ). Add $FreeBSD$ to rewinddir.c and seekdir.c.

Add a LIST_HEAD to DIR for a queue of telldir positions.

2000-12-06T03:14:28Z

Also add a location count (used as the magic for telldir) to DIR. A future change will also add a mutex/lock.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"

1999-12-29T05:07:58Z

is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Fixed missing declaration of getdents(2).

style fixes, remove extra braces.

readdir_r is not POSIX according to POSIX_SOURCE, bruce says: > readdir_r() is in the _POSIX_SOURCE section, but is not a POSIX.1-1990 > function. It's POSIX.1-1996 so it should be under a different feature > test which we don't support yet. make sure errno is saved so that its contents are cleared unless necessary. Submitted by: bde
