Reading from file without caring about \n

[krreks]

I have text files and want to read 1024 characters at the time, no matter if its \ns or something else.

Open your file using fopen() and the "rb" open mode and read all you want.

The fread works great for ascii/text files, but is no good for binary files (e.g. compiled c programs).

Is there a way that will work for all files?

Who told you that nonsense? Read my reply again (see above).

I've opened the file with mode: rb, but I'm still not able to read it properly.

while(!feof(input)) {
    if(!ferror(input)) {
        if(fread(inputBuffer, 1, MSG_MAX_LEN-1, input)) {
            printf("%d chars read \n", strlen(inputBuffer));
            reads++;
        }
    }
}

I'm trying to output this:

I know there a few thousand chars in the file, but the code above output:

7 chars read
0 chars read
4 chars read
0 chars read
6 chars read
12 chars read
1 chars read
15 chars read
17 chars read
28 chars read
0 chars read

12 chars read
//END OF OUTPUT

Why?

Why?

Because fread doesn't read C strings, it reads just bytes. Same as you want to
ignore end-of-line characters, the fread function doesn't interpret \0 characters,
i.e. it just reads them. Use the return value of the fread function itself.

You are reading the proper number of bytes. Don't forget that strlen terminates on a null which is represented as a binary 0. if the 5th byte of 1000 is a zero, strlen will terminate and return a value of 5. fread with the rb flag reads binary, anything, not just strings.
