libipfwc memory leak?

[Andriy T. Yanko <wireless@wireless.org.ua>]

Hi people!

I know that this letter is not for this mailllist. But I'm tired to find mistake.

I just writen this smal code for example:

--- cut ---
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>
#include <signal.h>
#include "libipfwc/libipfwc.h"


int main( int argc, char **argv)
{
    pid_t pid;

    unsigned int num_chains; 
    unsigned int num_rules; 
    static struct ipfwc_fwchain *chains;
    struct ipfwc_fwrule *rules;

    pid=fork();
    if ( pid == -1 ) { printf("Can't fork!\n"); exit(0); }
    if ( pid != 0) exit(0);
    setsid();

    while(1)
    {
	chains=ipfwc_get_chainnames(&num_chains); 
	rules=ipfwc_get_rules(&num_rules,0); 
	sleep(1);
    }
    
    return 0;
}
--- end ---

When program is runnig I just type command "ps aux" 
and I saw that my program get more and more system memory.

Is this memory leak of libipfwc library?

In  libipfwc.c  function ipfwc_get_chainnames & ipfwc_get_rules use malloc() but not use free().
It's maybe ok for program ipchains but in my case is not gut.

How to fix it?

THANKS IN ADVANCE.
