指针做为参数的传值

1. 要调用的函数含有char指针

int CreateNum(char *cPubKey，char *error)

调用传入的字符串

BYTE	AscData[1024];
CString			strTemp("takemetofunction");
memcpy(AscData, strTemp, strlen(strTemp));
char			*cPubKey=(char *)AscData;

char *str = (char *)malloc(sizeof(char) * 100);
//调用
CreateNum(cPubKey,str)

1. 要调用的函数含有byte指针

int		GetResult(BYTE* btpResult, int* npRetLen);

调用

BYTE	btRet[1024]; 
	memset(btRet, 0, sizeof(btRet));
	int nLen = 0;
	//调用
	int nResult = GetResult(btRet, &nLen);
