等价的C到fstream的的偷看 [英] C equivalent to fstream's peek

问题描述

我知道在C ++中，你能够通过使用下一个字符偷看： in.peek（）;

I know in C++, you're able to peek at the next character by using: in.peek();.

怎么会去这样想窥视当一个文件在C下一个字符？

How would I go about this when trying to "peek" at the next character of a file in C?

推荐答案

龟etc +的与ungetc 。也许是这样的：

fgetc+ungetc. Maybe something like this:

int fpeek(FILE *stream)
{
    int c;

    c = fgetc(stream);
    ungetc(c, stream);

    return c;
}
