lukem d896261208 back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.
1999-09-20 04:38:56 +00:00
lukem b48252f365 * use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
  and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

		_DIAGASSERT(path != NULL)
	#ifdef _DIAGNOSTIC
		if (path == NULL) {
			errno = EFAULT;
			return (-1);
		}
	#endif

sommerfeld 508d2d0e9e Avoid infinite loop if pathname is longer than the maximum the kernel
is willing to return from getcwd().
(this can only happen in -current).

sommerfe bb8c6c869a move __getcwd prototypes to libc-private header file.
XXX duplicate the prototype in getcwd regression test (which needs to
call the syscall directly for reasonably complete testing).

lukem 2b0e1bd9bd backout parts of the lite2 merge; it causes undesirable lossage:
* $PWD was used if it appeared ``correct''. this `enhancment' was
  not documented in getcwd(3), and caused problems for pwd(1) (which
  uses getcwd(3)), and in turn <bsd.obj.mk> (which uses pwd) when $PWD
  is set to the logical path instead of the real path (e.g, symlink
  /usr/src -> /z/NetBSD-current/src).
  [$PWD is set to the logical path by tcsh(1) with set symlinks=expand]
* as getcwd() without the $PWD code is just a wrapper to getcwd_physical(),
  rename the latter to the latter. hack realpath() to use the getcwd().

yet another case of `it was a good idea, but...'

jtc 43fa6fe319 If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore.  The library will use those
names internally.  Weak aliases are used to provide the original names
to the API.

This is only the first part of this change.  It is most of the functions
which are implemented in C for all NetBSD ports.  Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
