[Dev-C++] Thread function issue in a class.

[Raghunath Marella.S <ms...@ya...>]

Hi there,

I am facing a tricky problem. I have defined a class,
in which there are few funtions written for
implementing multithreading. I have a funtion named
"createThreads_()", which creates few threads. There
is another function declared in the class, "DWORD
WINAPI threadEntry_(LPVOID)". This function pointer
has been passed in the CREATETHREAD(..) call, which is
being raised as an error in VC++ compier. 
It gives the error like,
_________________________ 
error C2664: 'CreateThread' : cannot convert parameter
3 from 'unsigned long (void *)' to 'unsigned long
(__stdcall *)(void *)'
        None of the functions with this name in scope
match the target type
________________________

If I use any external function Thread Function(making
it as friend to the class) then compilation is
through, WHICH IS AS EXPECTED. 
Similarly, if I make the "threadEntry_(..)" in class
as STATIC and use it in CREATETHREAD(..) call then
also compilation is through. But making STATIC wont
serve my purpose. 
I can go ahead with using external function by making
int as friend to the class.

BUT HERE MY CONCERN IS WHY NOT POSSIBLE TO USE A
MEMBER FUNCTION AS THREAD FUNCTION?????

Will anyone pls clarify if you know the reason. 

thanks in advance, 

regards,
Raghunath Marella
