Re: no. of available threads

[Luke Howard <lukeh@PADL.COM>]

I don't think such an API exists. 

You could extend the thread pool API in libraries/libldap_r/tpool.c
with something akin to the following (completely untested, of course):

int
ldap_pvt_thread_pool_availablethreads( ldap_pvt_thread_pool_t *tpool )
{
	struct ldap_int_thread_pool_s *pool;
	int ret;

	if (tpool == NULL)
		return -1;

	pool = *tpool;

	if (pool == NULL)
		return -1;

	ldap_pvt_thread_mutex_lock(&pool->ltp_mutex);
	ret = pool->ltp_max_count - pool->ltp_open_count;
	ldap_pvt_thread_mutex_unlock(&pool->ltp_mutex);

	return ret;
}
