C File IO

Guys, I fail hard at file I/O in C. What I'm trying to do is this:

Open the file
Read the first six bytes of the file
Compare it to blah, where blah is a character array
If it equals blah, do this stuff, otherwise
Shift forward one byte in the file and repeat.

The shifting part is kind of like a queue: basically, you go from FILE[0-5] to FILE[1-6] then FILE[2-7] and so on and so forth until EOF.

Can someone help me? In b4 forced indentation, Ruby on Rails, Opera, do your own homework, etc.

Also, in b4 GOTO or GTFO.

what do you mean by bytes?  does stdio even do that?

Fuck OO. GOTO or GTFO.

I guess you just mean characters?

Basically just acquaint yourself with fseek and fgets:
fseek (the_file_stream, -4, SEEK_CUR) would set you to the point for the next read after an fgets(string, 6, the_file_stream).  Throw those together in a while construction and you should be set.

char buf[6];

FILE* f = fopen("file", "rb");
if (fread(buf, 1, sizeof buf, f) == 6 && memcmp(buf, "nigger", sizeof buf) == 0)

memmove(buf, buf + 1, sizeof buf - 1)
buf[5] = fgetc(f); //feel free to give a shit about EOF

That looks like it will work. Thanks a bunch.

I'm sure you meant while(...) there.

use strstr on blocks

Use Linux
