Hi,
If I try to compile a C program which uses rand_r with gcc 4.5.3, with
-std=c99, I get
warning: implicit declaration of function 'rand_r'.
Google gave me http://cygwin.com/ml/cygwin/2009-05/msg00417.html and
http://sourceware.org/ml/newlib/2007/msg00800.html, which explains why
this happens, but these messages are 3 years old. Additionally,
http://linux.die.net/man/3/rand_r suggests that rand_r is c99. Are
there plans to update stdlib.h to account for c99? If I look through
the http://linux.die.net/man pages and figure out which things are c99
and submit a patch, will it get checked in?
The Linux man page you point to has this to say about rand_r's conformance:
The function rand_r() is from POSIX.1-2001. POSIX.1-2008 marks rand_r()
as obsolete.
The fact that rand_r doesn't list c99 and is obsoleted in POSIX.1-2008
makes me dubious that newlib folks are going to jump at a patch to add
it to c99.
