error: sigqueue undeclared

Hi all,

I'm trying to port an API library to OS X. The library is already available under Unix/Linux/Windows. i can't compile some code now because it can't find 'sigqueue'. Anyone familiar with this function, and why it's not included? I believe this function should have been defined in <signal.h>, according to this: http://www.opengroup.org/onlinepubs/007908799/xsh/sigqueue.html

The headers and erroneous section for my code look like this:
------
#include <stdlib.h>
#include <time.h>
#include "oaDMFileSys.h"
#include "oaDMFileSysLocking.h"

#if !defined(WIN32)
#include <errno.h>
#include <signal.h>
#include <netdb.h>
#include <pwd.h>
#include <unistd.h>
#include <sys/utsname.h>
#endif

using namespace std;

.
.
.
.

bool
FileLocking::isActive(const ProcInfo    &p)
{
#ifdef WIN32
    HANDLE h = OpenProcess(PROCESS_ALL_ACCESS, false, p.id);
    if (!h) {
	return false;
    }
    CloseHandle(h);
    return true;

#else
    if (sigqueue(p.id, 0, sigval()) == -1 && errno == ESRCH) {
    	return false;
    }
    return true;
#endif
}

--------
It's the "if (sigqueue(p.id, 0, sigval())" statement that fails.
