Hi,

I need a help on this.
Here's a peace of code from BladeMP3EncDLL.c (from lame-3.97 project)


__declspec(dllexport) BE_ERR beWriteInfoTag( HBE_STREAM hbeStream,
											 LPCSTR lpszFileName )
{
	FILE* fpStream	= NULL;
	BE_ERR beResult	= BE_ERR_SUCCESSFUL;

	lame_global_flags*	gfp = (lame_global_flags*)hbeStream;
	
	
	if ( NULL == gfp )
	}
	if ( NULL != gfp )
	{
		// Do we have to write the VBR tag?
		if ( lame_get_bWriteVbrTag( gfp ) )
		{

			// Try to open the file
			fpStream=fopen( lpszFileName, "rb+" );

			.....


I'm calling this DLL from Delphi and it works just fine with non-unicode 
file names.

My question is how to change this C part so it will accept unicode 
filename and will open it as well. As I understand fopen does not work 
with unicode (or am I wrong?).

TIA
Eriks

Just a guess but try using _wfopen instead and define UNICODE in the project 
options.

Hi,

Thanks for idea. I changed  LPCSTR  to wchar_t *  and
fopen( lpszFileName, "rb+" ) to _wfopen( lpszFileName, L"rb+" ) and now 
it works. Didn't even have to define UNICODE.
