Thread: gets()

Is there an equal command to gets() in C. I am storing a string into a character array and am using gets(). So I have something like:

Code:

char dBuffer[100];

gets(dBuffer);

I would just like to know if this is about it or if there is another function that will do the same thing.

there is a gets() function in C but it is very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very bad. Read this to find out why

A much better function is fgets().

From the man page:

BUGS
Never use gets(). Because it is impossible to tell without knowing the data in advance how many characters gets() will read, and
because gets() will continue to store characters past the end of the buffer, it is extremely dangerous to use. It has been used to
break computer security. Use fgets() instead.

fgets() works in basically the same fashion as gets() but it is a lot safer.

Just read your link. I suppose buffer overflows might just be the thing to ruin my day

I just switched to fgets(), Thanks

>It has been used to break computer security.

can you explain how you can do that ?
