Reading a file in binary question

When reading a file in binary is there any way to have it stop at a delimiter such as '\n'. From what I've found you use read() but that only allows for the character array and the size of the array no delimiter. I was using getline but then when i switched to binary, that no longer worked so I assumed that since its binary, getline doesnt really get along with it.

I need to read it in binary and I need a way to search for a string within it. That's why I need to read line by line.

Any help that you can give is appreciated

Thanks,

Well fread() can read a file in binary because of how it works. It reads a file one item at a time, each item being of the same size. The man page gives a lot better of an explanation than me.
From the fread man page:

Quote:

---

#include <stdio.h>

size_t fread(void *ptr, size_t size, size_t nmemb, FILE *stream);

DESCRIPTION:
The function fread reads nmemb elements of data, each size bytes long,
from the stream pointed to by stream, storing them at the location
given by ptr.

Not exactly a test for newline, but you at least you are reading the file into a buffer responsibly without a significant risk of overflowing it. It's the fgets() of binary files. Please read thge manual.

Why do you need to read the file in binary?

If you need to search for '\n', then you could read a byte at a time, but I doubt that is the best option.

I don't see any reason to use fread in this C++ program.

It's really a C solution to a C++ problem. At least it does work, but I posted it in the wrong place. I hope someone forgives me for that...

I don't really see why file.get(char *buffer, streamsize num, char delim) wouldn't work either, now that I think of it; it reads byte-by-byte too, so it can work in binary mode.
