POSIX.2. What it does exactly varies considerably between systems,
particularly in where its prompt is displayed and where it gets its data

overflow buffers. (CWE-676, CWE-120, CWE-20). Make the specific calls to do
exactly what you want. If you continue to use it, or write your own, be

This C routine is considered obsolete (as opposed to the shell command by
the same name). The interaction of this function with SIGALRM and other
timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
