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.

timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
