C equivalent to fstream's peek

Question

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

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

Answer 1

you'll need to implement it yourself. use fread to read the next character and fseek to go back to where you were before the read

Answer 2

You could use a getc followed by an ungetc

Answer 3

fgetc+ungetc. Maybe something like this:

int fpeek(FILE *stream)
{
    int c;

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

    return c;
}
