Mac OS X support

[astavonin]

Current version is totally nonoperable on Mac OS X.

Mac OS X structures:

struct sockaddr {
__uint8_t sa_len; /* total length /
sa_family_t sa_family; / [XSI] address family /
char sa_data[14]; / [XSI] addr value (actually larger) */
};

struct sockaddr_in {
__uint8_t sin_len;
sa_family_t sin_family;
in_port_t sin_port;
struct in_addr sin_addr;
char sin_zero[8];
};

struct sockaddr_in6 {
__uint8_t sin6_len; /* length of this struct(sa_family_t)/
sa_family_t sin6_family; / AF_INET6 (sa_family_t) /
in_port_t sin6_port; / Transport layer port # (in_port_t)_/
_uint32_t sin6_flowinfo; / IP6 flow information /
struct in6_addr sin6_addr; / IP6 address _/
_uint32_t sin6_scope_id; / scope zone index */
};

Basically, I tried to fix the issue, but the total refactoring of the library have to be making for that..

Can you be more specific? I develop on OS X, and the tests pass for me. Do you have examples of what is not working?

[astavonin]

You export from the library sockaddr_in and etc structures which are wrong in case of Mac OS X. It is impossible to use it directly or in case of mixed C/C++ and Rus source code.

By directly I mean without using of getaddrinfo

[jdm]

Do you have an example piece of code to reproduce this problem?

#[test]
fn test_socket_bind() {
    let fd = c::socket(AF_INET, SOCK_STREAM, 0 as libc::c_int);
    let addr = {
        sin_family: AF_INET as i16,
        sin_addr: {s_addr: htonl( 0u32 )},
        sin_port: htons( 8088u16 ),
        sin_zero: (0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8, 0u8)};
    let res = c::bind(fd, ptr::addr_of(addr) as *sockaddr_storage, sys::size_of::<sockaddr4_in>() as socklen_t);
    assert res != -1 as libc::c_int;
}
