For the actual buffer processing, the function is perfectly capable of handling zero-sized buffers by simply returning.

对于实际的缓冲区处理，函数只需直接返回，就能够很好地处理大小为零的缓冲区。

This protects against stack, buffer, and function pointer overflows, all without recompilation.

这样将保护程序代码避免堆栈、缓冲区和函数指针溢出，而且全都不需重新编译。

In a similar fashion, you can read data segments off segment by segment from an abstract buffer with the following function.

采用类似的方式，您可以使用以下函数，逐段地从抽象缓冲区读取数据段。
