Can local variable be passed as the parameter for a new created thread procedure? Here is the example code:
There is another method using variable on the heap,
I test these code, both methods work as expected, but I doubt whether the first method is a good way. OR if only the second method is the correct way to pass a parameter to a thread. Thank you for help!
Code:
void CDLG::some_function()
{
CString strFileName="abc.doc";
//local variable, can it be valid for being passed into the following new thread???
//Can strFileName still be accessed from within the stack of thread procedure?
::AfxBeginThread(ProcessContentThread,(LPVOID)&strFileName);
}
UINT ProcessContentThread(LPVOID p)
{
CString* pstr=(CString*)p
CString strFile=*pstr;
//process the file
...
}Code:
void CDLG::some_function()
{
CString strFileName="abc.doc";
CString* pstrFN=new CString(strFileName);
::AfxBeginThread(ProcessContentThread,(LPVOID)pstrFN);
}
UINT ProcessContentThread(LPVOID p)
{
CString* pstr=(CString*)p
CString strFile=*pstr;
delete pstr;
//process the file
...
}
