C++ Syntax error - identifier not found

I have a file "injectdll.h", code:

#include <windows.h>
#include <tlhelp32.h>

void GetTargetThreadIdFromProcname(char *procName);

bool LoadDll(char *procName, char *dllName);

And a file "injectdll.cpp" with following code:

#include "StdAfx.h"
#include "injectdll.h"

void GetTargetThreadIdFromProcname(char *procName)
{
} 

bool LoadDll(char *procName, char *dllName)
{
  开发者_运维知识库  GetTargetThreadIdFromProcName(procName);
}

I cannot compile that simple piece of code:

error C3861: "GetTargetThreadIdFromProcName": Bezeichner wurde nicht gefunden. / 'identifier': identifier not found, even with argument-dependent lookup

Where's the error? It's driving me crazy...

You have camel-case ProcName in the call; the function is declared as Procname

In your posted code you have a capital on ...ProcName when you call it from within LoadDLL.
