[R] niceness

Can anyone tell me if the following C code (which proved very useful when
using the snow package -- use it to nice slaves) compiles and dyn.loads
under Windoze or Mac? It is (apparently) POSIX, so I suppose it is fine
in OS X, but does Windoze's advertized POSIX compliance mean anything here?
If it doesn't work on some platform, how do I deal with that? I want
to submit as contributed package to CRAN. The whole package can be found at
http://www.stat.umn.edu/geyer/nice_0.1.tar.gz
----- begin C code file -----
#include <sys/resource.h>
#include <errno.h>
#include <string.h>
#include <R.h>
void
get_my_priority(int *result)
{
errno = 0;
result[0] = getpriority(PRIO_PROCESS, 0);
if (errno != 0)
warning(strerror(errno));
}
void
set_my_priority(int *priority)
{
if (setpriority(PRIO_PROCESS, 0, priority[0]) != 0)
warning(strerror(errno));
}
------ end C code file ------
