用VC6，使用以下代码运行傲天API
int x=Startup("",8802, "192.168.0.1",8801,"test","test",
30,60,33000,1,5000,5,1,&PDeliver,&PReport,&PResponse,&PMTError);
一运行就出现异常,异常是file\i386\chkesp
下面是解决方法

//------自己定义的nsgip.h-------------
#define SGIPAPI __stdcall

typedef int (SGIPAPI *Startup_PTR)(char* cLocalIp, short iLocalPort,
char* cSmgIp, short iSmgPort,
char* cLoginName, char* cPassword,
int lSocketTimeOut, int lMTTimeOut,

int lMTThread, int lMaxListNode, int lMTMaxRetryTime, int lMOThread,
void (* fProcessDeliver)(DeliverStr deliver),
void (* fProcessReport)(ReportStr report),
void (* fProcessResponse)(MTRespStr response),
void (*fProcessMTError)(MTErrorStr mterror));

typedef int (SGIPAPI *Cleanup_PTR)();

typedef int (SGIPAPI *Submit_PTR)(
