 | hi,
I come across to the problem of ACE_OS::setsockopt with SO_REUSEADDR, in
5.4.3. Documention says Winsock2's support of SO_REUSEADDR is broken and
ignore
this option silently. It also says "ACE always sets SO_REUSEADDR = 1",
(aec/OS_NS_sys_socket.inl:841). Since ACE_OS::setsockopt is at lowest level
of all wrapper, how could ACE set that?
I grep the source code roughtly, and don't find any direct call to
::setsockopt.
So, how is that done?
--------------------------------------------------------------
There is another problem bothering me, but it is not related to ACE. Please
give me some advice, since you guys are solaris experts:
SO_REUSEADDR is not working on my solaris box, (solaris 9 sparc). Same
code works as expect on linux and windows. Here they are:
#include
#include
#include
#include
#include
// print error and clear errno
void Perror(const char* msg)
{
perror(msg);
errno = 0;
}
int main(int argc, char* argv[])
{
int lhdl, chdl;
struct sockaddr_in laddr, raddr;
int one = 1, size = sizeof(int);
laddr.sin_family = AF_INET;
laddr.sin_port = htons(5150);
laddr.sin_addr.s_addr = htonl(INADDR_ANY);
// I want two sockets both at same local port, one is listening and
another
// connecto to my server.
lhdl = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if( lhdl == -1) Perror("socket");
chdl = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if( chdl == -1) Perror("socket");
if( 0 != setsockopt(lhdl, SOL_SOCKET, SO_REUSEADDR,
&one, sizeof(int)))
Perror("setsockopt");
if( 0 != bind(lhdl, (struct sockaddr*)&laddr, sizeof(laddr)))
Perror("bind");
if( 0 != setsockopt(chdl, SOL_SOCKET, SO_REUSEADDR,
&one, sizeof(int)))
Perror("setsockopt");
if( 0 != bind(chdl, (struct sockaddr*)&laddr, sizeof(laddr)))
Perror("bind");
listen(lhdl, 5); Perror("listen");
raddr.sin_family = AF_INET;
raddr.sin_port = htons(80);
raddr.sin_addr.s_addr = inet_addr("202.38.215.238");
connect(chdl, (struct sockaddr*)&raddr, sizeof(raddr));
Perror("connect");
getchar();
return 0;
}
