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.
Suggested by: deischen
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().
is good for... :-)), I discovered that part of the change when mkstemps()
was brought in was missed - it was missing the termination case to make
sure it doesn't walk into the suffix. This isn't the same code OpenBSD
has, I think this is a little better as we terminate the loop in a better
spot.
leading XXX's. It could wrap an uppercase character through chars
like: [ \ ] ^ _ ` in between Z and a. The backslash and back tick
might be particularly nasty in a shell script context. Also, since
we've been using upper-case generated values for a while now, go with
the flow and use them in the pathname search rotation.
implement mkdtemp
improve man page for mk*temp
use arc4random to seed extra XXX's randomly
Optionally warn of unsafe mktemp uses

This should go into 2.2 after a testing period.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Added $Id$'s to files that were lacking them (gpalmer), made some
cosmetic changes to conform to style guidelines (bde) and checked
against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde)
One last code cleanup:-
Removed spurious casts in fseek.c and stdio.c.
Added missing function argument in fwalk.c.
Added missing header include in flags.c and rget.c.
Put in casts where int's were being passed as size_t's.
Put in missing prototypes for static functions.
Changed second args of __sflags() inflags.c and writehook() in vasprintf.c
from char * to const char * to conform to prototypes.
This directory now compiles with no warnings with -Wall under
gcc-2.6.3 and with considerably less warnings than before with the
ultra-pedantic script I used for testing. (Most of the remaining ones
are due to const poisoning).
The usual stuff, adding missing function prototypes, argument types,
return values, etc. In mktemp.c, convert pid from u_int to pid_t, and
get rid of "extern int errno".
