Thank you. 

However, it did not move well. 

If test.dll is done in LoadLibrary, Access Violation is generated. 

Are you still amused something?


[main source code]

#include "stdafx.h"
#include "windows.h"

#ifdef __cplusplus
extern "C"{
#endif

typedef int (*TFUNC)(void);

typedef void (*Tinit)(void);

int _tmain(int argc, _TCHAR* argv[])
{
	int i;

	HINSTANCE	h;
    	HINSTANCE	hInstDLL;

	Tinit		init;
	TFUNC		DllFunction;
	DWORD		ErrNo;

	h = LoadLibrary( TEXT( "cygwin1.dll" ) );
	init = (Tinit)GetProcAddress( h, "cygwin_dll_init" );

	init();

	hInstDLL = LoadLibrary( TEXT( "test.dll" ) );		/* !Access Violation! */
	if( hInstDLL == NULL )
	{
		ErrNo = GetLastError();
		return 0;
	}
	DllFunction = (TFUNC)GetProcAddress( hInstDLL, "hello" );
	i = DllFunction();

	FreeLibrary( hInstDLL );
	FreeLibrary( h );

	return 0;
}
