- Subject: Using rand_r
I'm trying to use the function rand_r with gcc-4 in Cygwin 1.7, all my
packages are up to date. It's supposed to be defined in stdlib.h, and I
can see it there. But if I compile a program which uses it, I get:
warning: implicit declaration of function 'rand_r'.
The reason seems to be the check for #ifndef __STRICT_ANSI__ in
stdlib.h. Even though I'm compiling with -std=c99, __STRICT_ANSI__ still
gets declared, so the definition of rand_r is unavailable. This seems to
be the same problem stated here:
Is this a bug or is rand_r supposed to be unavailable with C99?
