Hi Barry.
This is just a quick suggestion, but try moving the
apr_socket_timeout_set into the while(!terminate) loop, so it's called
everytime (works for me).

Hi All,
I am trying to create a UDP port that will only receive data, never
send. My problem is that even though I am setting the socket timeout to
a number greater than 0, the call to apr_socket_recv blocks and never
returns because of a timeout. This is causing my program to hang. Even
if another thread closes the socket, the recv method still blocks. Here
is some of my code below. Can anyone help? Thanks.
apr_pool_t *p;
apr_socket_t *sock;
apr_sockaddr_t *local_sa;
// create a pool
apr_pool_create(&p, NULL);
// create the address info
apr_sockaddr_info_get(&local_sa, NULL, APR_INET, notificationPort, 0,
p);
// create the socket
apr_socket_create(&sock, local_sa->family, SOCK_DGRAM, APR_PROTO_UDP,
p);
// set socket opts
apr_socket_opt_set(sock, APR_SO_LINGER, 1);
apr_socket_opt_set(sock, APR_SO_RCVBUF, 16384);
apr_socket_opt_set(sock, APR_SO_REUSEADDR, 1);
apr_socket_opt_set(sock, APR_SO_BROADCAST, 1);
// set timeout
apr_socket_timeout_set(sock, 1000000);
// bind socket to notification port
apr_socket_bind(sock, local_sa);
char datarecv[MON_APR_STRLEN];
string readbuff = "";
size_t maxLineSize = 8000;
while(!terminate)
{
apr_size_t length = MON_APR_STRLEN;
memset(datarecv, 0, MON_APR_STRLEN);
rv = apr_socket_recv(sock, datarecv, &length); // this will block
forever
