我试着用WSASocket动态链接winsock函数，下面的代码编译就好了

#include <stdio.h>
#include <winsock2.h>
#include <windows.h>
typedef SOCKET (WINAPI * pWSASocket)(int, int, int, LPWSAPROTOCOL_INFOA, GROUP, DWORD);
int main()
{
        HMODULE hmod = LoadLibrary("ws2_32.dll");
        if (hmod == NULL)
        {
                printf("Failed to load ws2_32.dll\n");
                exit(EXIT_FAILURE);
        }
        pWSASocket WSASocket = (pWSASocket)GetProcAddress(hmod, "WSASocket");
        if (WSASocket == NULL)
        {
                printf("Failed to find function WSASocket\n");
                exit(EXIT_FAILURE);
        }
        return 0;
}

但是当运行二进制文件时，我得到错误Failed to find function WSASocket
根据WINAPI文档，WSASocket应该在Ws2_32.dll中，但GetProcAddress返回NULL值
