hmmm, what i am doing is that i want to wrap my formated file read in a File class that i design myself so that it throws exceptions for every problem that might occur.
what i want to is to have a Scan method in my File class that looks like

void File:can ( const char * Format, ... )
{
va_list objArgs;
va_start( objArgs, pcFormat );
vfscanf( m_pFile, pcFormat, objArgs ); // m_pFile is the file handle
va_end( objArgs );
}

this is actually wraping fscanf in File:can
