Function does not check the second iterator for over-read conditions
(CWE-126). This function is often discouraged by most C++ coding standards
in favor of its safer alternatives provided since C++14. Consider using a
form of this function that checks the second iterator before potentially
overflowing it.

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.
