[Bug 25401] New: The Wine implementation of Winsock API (WSAStringToAddress) has a bug.

http://bugs.winehq.org/show_bug.cgi?id=25401

Summary: The Wine implementation of Winsock API
                    (WSAStringToAddress) has a bug.
           Product: Wine
           Version: unspecified
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winsock
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

According to MSDN description:

INT WSAStringToAddress(
__in LPTSTR AddressString,
__in INT AddressFamily,
__in LPWSAPROTOCOL_INFO lpProtocolInfo,
__out LPSOCKADDR lpAddress,
__in_out LPINT lpAddressLength
);
lpAddressLength
Length of the Address buffer, in bytes. Returns the size of the resultant
sockaddr structure. If the specified buffer is not large enough, the function
fails with a specific error of WSAEFAULT and this parameter is updated with the
required size in bytes.

when function call returns successfully, the parameter lpAddressLength should
have already been updated to the correct size of the address (for example: 16
for IPv4 address, 28 for IPv6 address). During our tests, the Wine
implementation doesn't update the parameter before its return. The parameter
remains unchanged (the input value of the parameter is usually larger than 16,
usually 128).
