7.19.7.7 The gets function
Because gets does not check for buffer overrun, it is generally unsafe to use when its input is not under the programmer’s control. This has caused some to question whether it should appear in the Standard at all. The Committee decided that gets was useful and convenient in those special circumstances when the programmer does have adequate control over the input, and as longstanding existing practice, it needed a standard specification. In general, however, the preferred function is fgets (see §7.19.7.2).
