是的。
是否使用fwrite ??
这就是你的意思''用来写一个精确的二进制文件
图片，是的。另一种方法是写一个
a文本版，一次一个成员。

第二个选项会更好，因为，AFAIK是一个精确的二进制图像
可能会遇到结构成员大小的问题，
编译器为结构成员选择的对齐方式
甚至是byte-endianness，如果输出文件要在不同的平台上使用。
我可能错了，想想，我很乐意如果我是在这里纠正。

Is it possible to write a structure to a file in c...as in c++...??
is it using fwrite??
thanx

Yes.

That''s what you''d use to write an exact binary
image, yes. Another way would be to write
a textual version, one member at a time.

The second option would be better, because, AFAIK an exact binary image
may have problems with the size of the members of the structure, with
the alignment choosen by the compiler for the members of the structure
and even byte-endianness, if the output file is to be used across
different platforms.
I may be wrong, thought, and I would love to be corrected here if I am.
