Socket::AncillaryData#int

ancillarydata.int => integer

static VALUE
ancillary_int(VALUE self)
{
    VALUE data;
    int i;
    data = ancillary_data(self);
    if (RSTRING_LEN(data) != sizeof(int))
        rb_raise(rb_eTypeError, "size differ.  expected as sizeof(int)=%d but %ld", (int)sizeof(int), (long)RSTRING_LEN(data));
    memcpy((char*)&i, RSTRING_PTR(data), sizeof(int));
    return INT2NUM(i);
}

Returns the data in ancillarydata as an int.

The size and endian is dependent on the host.

Example

ancdata = Socket::AncillaryData.int(:UNIX, :SOCKET, :RIGHTS, STDERR.fileno)
p ancdata.int #=> 2
