_beginthread / process.h

[fx9200]

hello, i'am creating threads to run some listeners, i have an error which i have not understanded the compiler says that _beginthread is undeclared but i have included process.h ?? this is the code #include #include /* _beginthread, _endthread */ #include #include void main() { HANDLE hThread; unsigned threadID; // Create the second thread. hThread = (HANDLE)_beginthread( NULL, 0, &SecondThreadFunc, NULL, 0, &threadID ); // Wait until second thread terminates. If you comment out the line // below, Counter will not be correct because the thread has not // terminated, and Counter most likely has not been incremented to // 1000000 yet. WaitForSingleObject( hThread, INFINITE ); // Destroy the thread object. CloseHandle( hThread ); return 0; }

Better use CreateThread().

i used it but when executing the function (with debugger) the parameter ( whose type is char*) pass directly to a NULL parameter . Note: the function is executing normally without thread !

Did you see example from this function in msdn?

From the MSDN
Example
The following example uses _beginthread and _endthread.

// crt_BEGTHRD.C
// compile with: /MT /D "_X86_" /c
#include 
#include     /* _beginthread, _endthread */
#include 
#include 
#include 
...
...

You get this error "c:\C\1112\Main.cpp(29): error C3861: '_beginthread': identifier not found, even with argument-dependent lookup" Did you see this line in this example // compile with: /MT /D "_X86_" /c

Did you set /MT /D "_X86_" /c to runtime library

[Hamid Taebi]

Right click in your project in solution Explorer ->select property->(Configuration properties)Open C/C++ ->code generation ->now you can see Runtime Library then select Multi-threaded Debug DLL (/MDd)

Open the Project Settings dialog (Alt+F7). Click the C/C++ tab. Select the Code Generation category. In the run-time library combobox, select Multithreaded (/MT) or Debug Multithreaded (/MTd).
