MSDN says
If this parameter is NULL, the variable is deleted from the current
process's environment.
So, NULL deletes it. And hence the C code should be like:
#if defined( HB_OS_WIN )
{
LPTSTR lpName = HB_TCHAR_CONVTO( szName );
LPTSTR lpValue = NULL;
HB_BOOL bResult;
if( ! ( szValue == NULL ) )
{
lpValue = HB_TCHAR_CONVTO( szValue );
}
bResult = ( SetEnvironmentVariable( lpName, lpValue ) != 0 );
HB_TCHAR_FREE( lpName );
if( lpValue != NULL )
HB_TCHAR_FREE( lpValue );
return bResult;
}
It is not optimized, please check.
