如何將一個CString類型的變量內容傳遞到一個帶指針類型參數的函數中?

[xhwu3721]

如下:
CString recdata;
recdata內有一些數據"01234567899".
我想將其寫入一個文件中,已經有一個函數,是
WriteMyLog(char *log);
我直接這樣不行,WriteMyLog(recdata);
應如何轉換一下呢?

1、WriteMyLog((LPSTR)(LPCTSTR)recdata);

2、或者重载WriteMyLog()函数

WriteMyLog(CString &str)

WriteMyLog((LPCTSTR)recdata);

不行,出現如下錯誤:
--------------------Configuration: SimuFax - Win32 Debug--------------------

Conversion loses qualifiers

WriteMyLog( recdata.GetBuffer(0) );

[bluebohe]

WriteMyLog((LPSTR)(LPCTSTR)recdata);

[fireant25]

int Length=recdata.GetLength();
LPTSTR p=recdata.GetBuffer(Length);
char* PInfo=NULL;
PInfo=(char*)p;
WriteMyLog(PInfo);

[fireant25]

int Length=recdata.GetLength();
LPTSTR p=recdata.GetBuffer(Length);
char* PInfo=NULL;
PInfo=(char*)p;
WriteMyLog(PInfo);
recdata.ReleaseBuffer();

[AaronChan]

int length = recdata.GetLength();
char *psztemp = new char[length+1]
memset(psztemp, 0, sizeof(psztemp));
lstrcpy(psztemp,(LPCTSTR)recdata);
WriteMyLog(psztemp);

thanks!

一句话就可以了:
WriteMyLog( recdata.GetBuffer( recdata.GetLength() ) );
