该程序在windows和linux下编译都会提示

我是新手，实在找不出问题在哪里。是不是MWGateway.dll 和libMWGateway.so 里的函数原形参数定义有问题？
我得到的SDK说明里都是类似int __stdcall MGhexChrTosrcStr(const char* srcMsg,char* retMsg) 形式的参数传递。是不是说明文档和实际动态库中定义不符？还是我哪里弄错了？

还有个问题是在windows下程序执行后能顺利连接到服务器并成功发送短信到我的手机上，但在linux下连接服务器失败，返回的错误也有好几种。这个项目很简单，不想拖久了，请各位高手帮忙，不胜感激！

GetProcAddress的第一个参数是HANDLE，你传入的是VOID*
MGhexChrTosrcStr的第二个参数是char*,你传入的是char[255]...

[qsxiaoyao]

谢谢您，请问应该怎么改了？我试着改了这些参数，但还是一直这样提示错误，我太菜了，呵呵

[qsxiaoyao]

刚查了下
WINBASEAPI FARPROC WINAPI GetProcAddress(IN HMODULE hModule, IN LPCSTR lpProcName);
typedef HINSTANCE HMODULE;
typedef void *HMODULE;
typedef void *HINSTANCE;

这里的handle应该是HMODULE型的，为void*,是我命名有问题。

第二个参数我实在不知道该怎么改。。。新各位朋友帮帮忙， 不胜感激

[qsxiaoyao]

呵呵，找到原因了，
int (__stdcall *MongateCsGetSmsEx)(int sock, char strMsg[500][255]);
int (__stdcall *MongateCsGetStatusReportEx)(int sock, char *strMsg);
int (__stdcall *MGhexChrTosrcStr)(const char* srcMsg[255],char* retMsg[255]);
我竟然这样声明的函数，呵呵
