    dll issue

    i have a dll that keeps locking up when i call the function sock_init() and i have no idea why. i'll post the code and if anyone can answer i'll appreciate it.

    PHP Code:
    #include "dll.h"
    #include <windows.h>

    using namespace std;

    export double sock_init()
    {
        
    WSADATA w;
        
    int error WSAStartup(0x0202, &w);

        if (
    error)
        {
            
    WSACleanup();
            return (
    static_cast<double>(0));
        }

        if (
    w.wVersion != 0x0202)
        {
            
    WSACleanup();
            return (
    static_cast<double>(0));
        }

    dll.h
    PHP Code:
    #ifndef _DLL_H_
    #define _DLL_H_

    #define export extern "C" __declspec (dllexport)

    #if BUILDING_DLL
    # define DLLIMPORT __declspec (dllexport)
    #else 
    # define DLLIMPORT __declspec (dllimport)
    #endif 


    class DLLIMPORT DllClass
    {
      public:
        
    DllClass();
        
    virtual ~DllClass(void);

      private:

    };


    #endif

    If you have not already done so, read this very carefully, especially the remarks paragraph.
