Wink gcc says "the `gets' function is dangerous and should not be used."

Is this just because it truncates an overrun of the input, or is there a more sinister problem with the gets function?

Sorry that this is such a basic question, but I'm just getting started in C.

Regards,

James

The short answer is don't use gets but fgets.
For details, google "buffer overflow exploits gets".

Ahhh I thought it might be more complicated than the truncation thing. I guess the book I'm learning from is a bit out of date...
