Function Documentation

void input_open_file_helper	(	service_ptr_t< file > &	p_file,
		const char *	p_path,
		t_input_open_reason	p_reason,
		abort_callback &	p_abort
	)

Helper function for input implementation use; ensures that file is open with relevant access mode. This is typically called from input_impl::open() and such.

Parameters

p_file	File object pointer to process. If passed pointer is non-null, the function does nothing and always succeeds; otherwise it attempts to open the file using filesystem API methods.
p_path	Path to the file.
p_reason	Type of input operation requested. See: input_impl::open() parameters.
p_abort	abort_callback object signaling user aborting the operation.

        case input_open_decode:
            filesystem::g_open(p_file,p_path,filesystem::open_mode_read,p_abort);
            break;
        case input_open_info_write:
            filesystem::g_open(p_file,p_path,filesystem::open_mode_write_existing,p_abort);
            break;
        }
    } else {
