Problem writing thread program in Solaris

[Roddman]

I writing a program creating a virtual circle with n
threads, they execute one by one, printing their id
and sending a signal to the next.
Basically, I need to create n number of threads, each receiving a
different parameter, zero to n-1, which is going
to be each thread’s id. I need to create an array of cond_t variables
using malloc (n * sizeof (cond_t)). How do I make n number of threads?
Also, am I using malloc correctly?
This is the psuedo code I have so far:

#include <stdio.h>
#include <thread.h>
#include <synch.h>

mutex_t	mp;
cond_t	cp;
malloc (n * sizeof (cond_t));


int main()
{
	int i;

	mutex_init (&mp, 0, NULL);
	cond_init (&cp, 0, NULL);
	thr_create(NULL, i, loop, (void *) NULL, NULL, NULL);

	for(i = 0, i>n, i++)
	{
		
	}
}
void*
loop(void* arg)
{
	if(id = 0)
	{
		printf("%s\n", id);
		sleep(5);
		cond_signal(&cp[i]);
		mutex_lock(&mp);
		cond_wait();
		mutex_unlock(&imp);
	}
	else
	{
		mutex_lock(&mp);
		cond_wait(&cp[i]);
		mutex_unlock(&mp)
		printf("%s\n", id)
		sleep(5);
		cond_signal(id+1)%n;
	}
