无效的函数参数

我正在写一个C代码，其中我使用套接字。我在Windows和Linux上使用它，所以我尝试动态编写它。我写了两个函数来获取服务器/客户端套接字。在那里，我对编译错误：无效的函数参数

debian:~/cross_socket# make 
gcc *.c -Wall 
i586-mingw32msvc-gcc *.c -Wall -lws2_32 
socket.c: In function 'get_client_socket': 
socket.c:28: warning: passing argument 3 of 'get_socket' from incompatible pointer type 
socket.c:13: note: expected 'int (*)(SOCKET, const struct sockaddr *, int)' but argument is of type 'int (*)(SOCKET, const struct sockaddr *, int)' 
socket.c: In function 'get_server_socket_addr': 
socket.c:43: warning: passing argument 3 of 'get_socket' from incompatible pointer type 
socket.c:13: note: expected 'int (*)(SOCKET, const struct sockaddr *, int)' but argument is of type 'int (*)(SOCKET, const struct sockaddr *, int)'

GCC对我的本地系统的伟大工程，但如果我使用的MinGW我得到这个错误？！？它说：我用int (*)(SOCKET, const struct sockaddr *, int)而不是int (*)(SOCKET, const struct sockaddr *, int) ...？

这里的相关代码：

inline SOCKET get_socket(uint16_t port, in_addr_t socket_in_addr, int (*create)(SOCKET, 
const struct sockaddr*, socklen_t)) { 
     SOCKADDR_IN addr; 
     SOCKET result_socket = GET_SOCKET; 
     if (SOCKET_NOK(result_socket)) 
       return SOCKET_INIT_ERROR; 
     memset(&addr, 0, sizeof(SOCKADDR_IN)); 
     addr.sin_family = AF_INET; 
     addr.sin_port = htons(port); 
     addr.sin_addr.s_addr = socket_in_addr; 
     if (CONNECT_NOK(create(result_socket, (SOCKADDR*)&addr, sizeof(SOCKADDR)))) 
       return SOCKET_INIT_ERROR; 
     return result_socket; 
} 

SOCKET get_client_socket(char* target, uint16_t port) { 
     return get_socket(port, inet_addr(target), &connect); 
/*  SOCKADDR_IN addr; 
     SOCKET client_socket = GET_SOCKET; 
     if (SOCKET_NOK(client_socket)) 
       return SOCKET_INIT_ERROR; 
     memset(&addr,0,sizeof(SOCKADDR_IN)); 
     addr.sin_family = AF_INET; 
     addr.sin_port = htons(port); 
     addr.sin_addr.s_addr = inet_addr(target); 
     if (CONNECT_NOK(connect(client_socket, (SOCKADDR*)&addr, sizeof(SOCKADDR)))) 
       return SOCKET_INIT_ERROR; 
     return client_socket;*/ 
} 

SOCKET get_server_socket_addr(uint16_t port, in_addr_t socket_in_addr) { 
     return get_socket(port, socket_in_addr, &bind); 
/*  SOCKADDR_IN addr; 
     SOCKET server_socket = GET_SOCKET; 
     if (SOCKET_NOK(server_socket)) 
       return SOCKET_INIT_ERROR; 
     memset(&addr, 0, sizeof(SOCKADDR_IN)); 
     addr.sin_family = AF_INET; 
     addr.sin_port = htons(port); 
     addr.sin_addr.s_addr = socket_in_addr; 
     if (CONNECT_NOK(bind(server_socket, (SOCKADDR*)&addr, sizeof(SOCKADDR_IN)))) 
       return SOCKET_INIT_ERROR; 
     return server_socket;*/ 
}

有没有人的想法？
